AI Technical Summary

Technical Problem

Existing sealing structures face issues with deformation of resin components due to gasket reaction forces, leading to compromised sealing performance.

Method used

A sealing structure with a gasket arranged in a receiving groove between two members, one of which is made of resin, and locking portions on both sides of the groove width direction that engage with corresponding locking portions on the other member to prevent separation, maintaining sealing performance.

Benefits of technology

The configuration suppresses deformation of the resin member and maintains sealing integrity by preventing separation of the components.

Abstract

To provide a combined body and a sealing structure that even when one member out of two member is made of resin, can suppress deformation of the one member to maintain sealing performance.SOLUTION: A combined body 1 comprises: a first member 2, at least one of two members to be assembled together being made of resin; a second member 3, which is the other of the two members; a gasket 6 arranged in a receiving groove 25 provided in the first member, and coming into elastic contact with the second member. One of the first member and the second member is provided with a pair of locking parts 4, 4 on both sides in a groove width direction of the receiving groove, which is respectively locked to a pair of locked parts 5, 5 provided on the other member, and prevents the first member and the second member from being displaced in a direction of separating each other.SELECTED DRAWING: Figure 1
