課題もあった。SUMMARY OF THE INVENTION In the prior art,
As shown in FIG. 4, a groove 24 is formed in the housing side wall 21 and the groove 2 is formed.
Since the rubber packing 23 is interposed in 4 and brought into surface contact, it is necessary to increase the side wall surface width L in order to mount the rubber packing. Also in FIG. 5, since the rubber packing 13 has a structure in which the rubber packing 13 is brought into surface contact with the inclined surfaces facing the case side wall 11 and the case side wall 12, a sufficient load is required when making a surface contact, and the load is small. However, there is a problem that sufficient waterproofing cannot be obtained when the side wall of the housing is connected to the vehicle. Furthermore, the housing side wall 11
There is also a problem that the rubber packing is displaced due to the structure having the rubber packing between the inclined surfaces facing the housing and the housing side wall 12, and it is difficult to align the rubber packing with the housing.
