The position of the two end portions 61 of the oil guiding member 60 corresponds to the position of the two bottom ends 511 of the oil storage tank 50, and the lead portion 62 of the oil guiding member 60 protrudes from the oil storage space 51. The oil guiding member 60 is made of wool felt or other material capable of generating a capillary phenomenon; the heat conducting member 70 is opposite The port 52 of the oil storage tank 50 is shaped into a shape, and a conductive portion 71 is formed on one surface of the heat conducting member 70. The conductive portion 71 has a through hole 711. The heat conducting member 70 is fixedly disposed at the port 52 of the oil storage tank 50 and abuts against the port 52 of the oil storage tank 50. The abutting edge 53 is disposed, and the heat conducting member 70 closes the port 52 of the oil storage tank 50, and the oil guiding member 60 is disposed adjacent to the heat conducting member 70, and the lead portion of the oil guiding member 60 in the oil storage tank 50 is disposed. The through hole 711 of the conductive portion 71 of the heat conducting member 70 is formed. The heat conducting member 70 is made of aluminum, copper or other metal material having thermal conductivity, and the thermal conductivity of the heat conducting member 70 is greater than the heat conductivity of the oil storage tank 50.

The action of the oil; on the contrary, when the relative movement and thermal energy between the moving member 40 and the long shaft 30 start to be generated, the viscosity of the lubricating oil in the oil storage tank 50 is lowered, and the oil guiding member 60 starts to generate the oil guiding action. The lubricating device can automatically change the state of the oil guiding or not, and does not need other control devices or components to achieve the same, and can avoid the continuous oil guiding when the moving member 40 and the long shaft 30 are not actuated, completely avoiding oil leakage. The condition occurs; and the oil guiding member 60 for guiding the oil is provided with the end portion 61 corresponding to the bottom end 511 of the oil storage tank 50, so that the oil guiding member 60 can surely guide the lubricating oil in the oil storage tank 50 sufficiently.
