In addition, a flow port 116 through which air flows is formed in the swirler installation part 110. The flow opening 116 may be understood as an opening through which air that has passed through the swirler 300 flows through the base plate 100. The shape and number of the flow holes 116 may be provided differently depending on the design.

In addition, an auxiliary intake part 130 formed on one side of the swirler installation part 110 is formed on the base plate 100. As shown in FIG. 4, the auxiliary intake part 130 may be formed on both sides of the swirler installation part 110, respectively. In addition, the second oil filter 115 is mounted on the auxiliary intake unit 130.

The auxiliary intake unit 130 may be understood as a configuration that facilitates the flow of air flowing by the swirler 300. In detail, the exhaust efficiency may be increased as air flows not only to the flow port 116 but also to the auxiliary intake unit 130. In addition, the auxiliary intake part 130 may extend to one side and have an open grill shape.

In addition, the base plate 100 includes a slit 112 formed by opening. The slit 112 corresponds to an opening into which at least a part of the filter bracket 200 is inserted. That is, the slit 112 may be understood as an opening to which the filter bracket 200 is coupled.

That is, the slit 112 is formed outside the swirler installation part 110. As shown in FIG. 4, the slit 112 is formed to extend along the outer circumferential surface of the swirler installation unit 110 in a radial direction outside of the swirler installation unit 110.

In addition, the slits 112 are formed in plural. For example, as shown in FIG. 4, the number of slits 112 may be provided in four. Each slit 112 is provided with the same size and shape, and is formed to be spaced apart at equal intervals in the circumferential direction. In this case, the number of the slits 112 corresponds to an example.

In addition, the base plate 100 includes a fastening hole 113 formed by opening. The fastening hole 113 corresponds to an opening into which a predetermined fastening member passing through the filter bracket 200 is inserted. That is, the fastening hole 113 may be understood as an opening coupled by the filter bracket 200 and the fastening member.

The fastening hole 113 may correspond to a circular opening into which a predetermined fastening member is inserted. For example, the fastening hole 113 may correspond to a small hole into which a screw is inserted.

At this time, the fastening hole 113 is disposed to be spaced apart from the slit 112 in the radial direction. In detail, the fastening hole 113 is formed outside the slit 112. That is, the fastening hole 113 is formed outside the swirler installation part 110, and the slit 112 is disposed closer to the rotation hole 114 than the fastening hole 113.

In other words, the rotation hole 114, the slit 112, and the fastening hole 113 are sequentially arranged in one direction. At this time, one direction corresponds to the outer radial direction of the circle formed around the rotation hole 114.

In addition, the fastening hole 113 is formed in plural. For example, as shown in Figure 4, the fastening hole 113 may be provided in four. Each fastening hole 113 is provided with the same size and shape, and is formed to be spaced apart at equal intervals in the circumferential direction. In this case, the number of the fastening holes 113 corresponds to an example.

In addition, the slits 112 and the fastening holes 113 may be provided in the same number. This is for the convenience of coupling with the filter bracket 200 to be described later. That is, each of the fastening holes 113 may be formed outside the plurality of slits 112 in the radial direction.

In this case, both the slit 112 and the fastening hole 113 correspond to an opening for coupling with the filter bracket 200. However, the filter bracket 200 is inserted into the slit 112, and a fastening member coupled to the filter bracket 200 is inserted into the fastening hole 113. That is, it can be seen that the filter bracket 200 is fitted through the slit 112 and fixed through the fastening hole 113.
