One recess 252 is a portion provided on the outer wall 221 of the housing 220 and into which the convex portion 251 is fitted. Specifically, the screw inlet of the screw 130 in each of the two screw holes 221b is referred to as a cylindrical convex portion. The convex portion 251 is a counterbore hole expanded to a diameter that allows it to be fitted. The screw hole 221b is formed from the bottom of the recess 221b which is a counterbore hole to the inner surface of the outer wall 221.

When attaching the connector 110 with the O-ring 140 to the housing 220, first, the housing 111 of the connector 110 is inserted into the through hole 121a in the outer wall 221 of the housing 220. Then, the two mounting holes 213a in the mounting portion 213 overlap the two screw holes 221b on a one-to-one basis, and the two convex portions 251 are fitted into the two concave portions 221b.

It is a counterbore hole. According to this regulation structure 250, rotation can be regulated with higher strength than, for example, when a convex portion or the like projecting from a part of the inner edge of the mounting hole 213a is provided. Further, since the recess 252 as the counterbore hole is easy to process, it is possible to reduce the difficulty in processing when providing the regulation structure 250.

Two regulatory structures 250 are illustrated to correspond to one. However, the regulation structure is not limited to this, and even if the convex portion is provided only for a part of a plurality of mounting holes and the concave portion is provided so as to correspond to such a convex portion. Good. However, since one convex portion 251 is provided for each mounting hole 213a and one concave portion 252 is provided so as to correspond to such a convex portion 251, deterioration of waterproof performance can be further suppressed. The points are also as described above.

Further, in the first and second embodiments described above, as an example of the mounting portion, mounting portions 113 and 213 formed as separate parts from the housing 111 and fixed to the housing 111 are exemplified. However, the mounting portion is not limited to this, and may be one that is integrally molded with the housing with resin or the like. However, as described above, the attachment portions 113 and 213 are formed as separate parts from the housing 111, so that the wear of the attachment portion can be suppressed.
