Cap attaching structure

摘要

A cap attaching structure includes a cylindrical member and a cap member. The cylindrical member has an end plate, a side wall to be inserted into the cylindrical member, and an engagement claw piece in which a proximal end portion is connected to an inserting side end portion of the side wall, while a distal end portion extends towards the end plate via a slit. On an outer circumference of the engagement claw piece, a claw portion adapted to be brought into engagement with an engagement hole of the cylindrical member is provided. The distal end portion of the engagement claw piece is disposed in a cutout portion in the end plate.

主权项

1. A cap attaching structure including:
a cylindrical member; and a cap member which is attached to an opening portion of the cylindrical member, wherein the cylindrical member has an engagement hole in a circumferential wall at a position close to the opening portion thereof, wherein the cap member includes:
an end plate which is disposed in the opening portion;a side wall which extends from a circumferential edge of the end plate so as to be inserted into the cylindrical member; andan engagement claw piece which has
a proximal end portion which is connected to an inserting side end portion of the side wall,a distal end portion which extends from the proximal end portion towards the end plate via a slit formed in the end plate and the side wall so as to constitute a free end, anda claw portion which is formed on an outer circumference of the engagement claw piece so as to be brought into engagement with the engagement hole of the cylindrical member, and wherein the distal end portion of the engagement claw piece is disposed in a cutout portion in the end plate via the slit, so that a deflection of the engagement claw is restricted through an abutment with the cutout portion in the end plate.
