That is to say, recently, with the development of small electrical components and thinner electrical parts, there is a problem that the above methods cannot be used due to the limited elastic (spring) stress of the metal plate or the limitation of the external dimensions. In addition, since the elastic (spring) load is concentrated on the point of the cam 邛 engaged with and disengaged from the engaging portion, there is a problem that the cam portion is deformed and the mechanical life is shortened. [Summary of the Invention] The purpose of the second invention is to solve the above-mentioned problems and provide-^ force * ^ parts, ^ increase the number of components, and only use the existing components, namely the moon dagger, to increase the torque of the pawl. Package: Solution = ”, in the present invention, the first solution is a housing of a plurality of solid portions; the contact point“ center ”disposed on the inner bottom surface of the receiving portion; a driving member on the lower side The cover member is held in sliding contact with the fixed contacts; the cover member is rotatably received in the above-mentioned receiving section, and the operation section centered on the upper side of the driving member will protrude through a through-hole of 99329.doc 200537537 and be inserted into the cover member. Connected to the upper side of the Shangcheng private chain ^ " the upper side of the body; at the periphery of the driving member, a ring-shaped continuous 疋 shell 扪 concave-convex cam portion is formed, and a small pair of side edges of the cover are formed to form a small Chengxing has a pair of pawl pieces that engage with the cam portion to give a tactile response. In addition, a second solution is to form the cam portion 'on the outer peripheral side portion of the drive member and bend the cover member downward. Side edge portions to form opposing _ 对 蛮 曲 士 对 # curved plates, the detent pieces are formed opposite to each other on the curved plates, and the cam portions are held between a pair of the detent pieces. Make it fit. In addition, the third solution The case structure is such that the pawl piece is formed in a double cantilever shape with both ends held on the curved plate. In addition, the fourth solution is constituted so that the cover member and the side edge forming the pawl piece are formed. A pair of opposite side edge portions is formed with a pair of mounting plates, and when the cover member is fitted on the upper side of the casing, the pair of mounting plates are engaged with the side portions of the casing. The fifth solution is to form the cover member with a thin metal sheet having elasticity. As described above, the rotary electrical component of the present invention includes a housing having a housing portion and a large number of housings disposed on the inner bottom surface of the housing portion. A fixed contact, which is fixed to the lower side; a sliding contact in which the sliding contact of the contact is rotatably accommodated in the accommodating part, and a through hole having an operation part protrudingly provided on the upper side of the driving part A cover member which is engaged with the upper surface side of the casing, forms a ring-shaped continuous concave-convex cam portion at a peripheral portion of the driving member, and engages with the cam portion at a pair of side edge portions of the facing member. 99329.doc 200537537 A pair of pawl pieces that generate a click feel, so by providing a pair of engaging pawl pieces that are opposite to the cam portion of the driving member, the spring load applied to the cam portion can be doubled as before. Therefore, there is no need to increase the number of members, and the torque of the click response can be increased by using only the existing members. In addition, the cam member is formed on the outer peripheral side portion of the driving member and the side edge portion of the cover member is bent downward. The pair of opposing bending plates are formed with pawl pieces facing each other on the bending plates. The cam portion is held between the pair of pawl pieces and the two are engaged with each other. Therefore, the driving member is provided on the bending plate. Upper-to-the pawl piece applies a force to the outer peripheral side surface portion from both sides toward the center of the axis of the operation portion evenly, so the rotation of the driving member is smooth and the operation feeling is good. In addition, the inclination of the driving member can be suppressed. In addition, since the pawl piece is formed in a double cantilever shape with both ends held on the curved plate, a load is applied to the center of the pawl piece evenly, so that the driving member can be rotated smoothly, and the mechanical life can be improved. In addition, it is easy to increase the torque. In addition, because a cover receiving member is formed on a pair of opposite side edge portions of the cover member that are different from the side edges forming the pawl piece, the mounting plate 212 is mounted on the upper side of the casing ... Therefore, the pawl pieces provided on the cloud and the current cow and the clothes board with the case card are provided on the side edge portions that are not in contact with each other, so that the cover member can be securely installed on the case. In addition, since the above is formed by using a thin metal sheet having elasticity, it is possible to form the cover member 1 'in one body.
