<p>A waterproof case is formed by connecting opening ends of first and second case members composed of a resin molded product to each other, in which an inner wall part having engaging holes, an outer wall part surrounding the inner wall part, a ring-shaped recess which is formed between both of the wall parts and into which a predetermined amount of adhesive is filled are formed at the opening end of the first case member, and a rear end position of the engaging hole along an axial direction is set so as not to be positioned at a rear end side more than a leading end of the outer wall part. A thin walled portion which is fitted around the inner wall part to be inserted into the ring-shaped recess, a thick walled portion which is continuously formed to the rear end of the thin walled portion and whose partial portion is inserted into the ring-shaped recess, and protrusions which protrude from an inner circumferential surface of the thick walled portion to be snap-fitted into the engaging holes are formed at the opening end of the second case member.</p> |
