Structure for attaching gasket

Abstract

A gasket of an elastic material is housed in a ring-shaped groove formed on the front face of a flange of a connector housing. By bringing the front face into contact with a contact face of a mating member, the space between the mating member and the flange of the connector housing is sealed with the gasket. An L-shaped locking arm is provided on the outer periphery of the ring-shaped gasket to be housed in the ring-shaped groove. The locking arm juts out sideward along the front face of the flange, and then is bent backward leaving the front face. A T-shaped hook is integrally provided to the tip of the locking arm. A receiving portion with a locking slot is provided in a side portion of the flange. The locking arm is engaged, by its own elasticity, with the locking slot, and the hook is engaged with the back face of the receiving portion.

Claims

1. A structure for attaching a gasket comprising: an attaching member including a first flange which has a ring-shaped groove formed in the front face, and which has a receiving portion with a locking slot formed on a side portion;a mating member including a contact face to be brought into contact with the front face of the first flange; andan elastic gasket housed in the ring-shaped groove, and used to seal a space between the first flange and the mating member,wherein the gasket includes a ring-shaped gasket body housed in the ring-shaped groove; a locking arm provided on the outer periphery of the gasket body; and a hook portion integrally formed on the tip of the locking arm, andthe locking arm is engaged with the locking slot from a side of the flange by use of the elasticity of the very locking arm, and the hook portion is engaged with the back face of the receiving portion.

2. The structure for attaching a gasket as recited in claim 1, wherein the locking arm has an L-shape, in which the locking arm juts out sideward along the front face of the flange, and is then bent backward leaving the front face of the first flange, andthe hook portion has a T-shape.

3. The structure for attaching a gasket as recited in claim 1, further comprising a cover member which covers the attaching member from the back, and which includes a second flange having a recess in the front face, wherein the first flange is fitted to the recess so that the receiving portion, the locking arm and the hook portion are housed in a portion of the recess, and that the hook portion is interposed between and compressed by the attaching member and the cover member.

4. The structure for attaching a gasket as recited in claim 1, wherein the gasket includes a locking jutting piece having a through-hole, the locking jutting piece being integrally formed on the inner periphery of the gasket body, andthe through-hole is fitted to a locking pin which is provided as jutting out of the flange at an inner position than the ring-shaped groove.
