Abstract

Official abstract text for this publication.

A sealing structure includes a first member ( 200 ) having a fitting groove ( 220 ); a second member ( 300 ) fixed to the first member ( 200 ); and a gasket ( 100 ) fitted to the fitting groove ( 220 ) to seal a gap between opposing surfaces of the first member ( 200 ) and the second member ( 300 ), wherein a plurality of locking protrusions ( 230 ) are provided on one of two sidewalls of the fitting groove ( 220 ), the locking protrusions ( 230 ) being spaced from each other and arranged along the direction in which the fitting groove ( 220 ) extends, and the gasket ( 100 ) is provided with a plurality of locked protrusions ( 120 ), the locked protrusions ( 120 ) being engageably locked against the respective locking protrusions ( 230 ) from a groove bottom side of the fitting groove ( 220 ).

First claim

Opening claim text (preview).

The invention claimed is: 1. A sealing structure comprising: a first member having a fitting groove; a second member fixed to the first member; and a gasket fitted to the fitting groove to seal a gap between opposing surfaces of the first member and the second member, wherein a plurality of locking protrusions are provided on one of two sidewalls of the fitting groove, the locking protrusions being spaced from each other and arranged along the direction in which the fitting groove extends, the gasket is provided with a plurality of locked protrusions, the locked protrusions being engageably locked against the respective locking protrusions from a groove bottom side of the fitting groove, a plurality of supporting protrusions are provided on another of the two sidewalls of the fitting groove at respective positions opposing the plurality of locking protrusions, the supporting protrusions supporting respective opposite sides of portions of the gasket on which the locked protrusions are provided, and a distance from the one of two sidewalls to a tip of the supporting protrusion on the fitting groove is set to be longer than a distance from a tip of the locked protrusion to a back side thereof on the gasket. 2. The sealing structure according to claim 1 , wherein the plurality of supporting protrusions are located and configured to compress the gasket against the locking protrusions when the gasket is fully inserted into the fitting groove.
