<P>PROBLEM TO BE SOLVED: To provide a technology for preventing rotation of a gasket and securing pressure that the gasket gives to a joint surface. <P>SOLUTION: A gasket is mounted in a groove formed in a first member and has elasticity for sealing between the first member and a second member. The gasket includes a first abutting part abutted to the second member, a second abutting part abutted to one sidewall surface of the groove, a third abutting part abutted to another sidewall surface of the groove, and a fourth abutting part in which protruded parts are formed which are protruded in a depth direction of the groove while being bisected in a depth direction of the groove, and in which distal ends of the two protruded parts are abutted to a bottom surface of the groove. The gasket is formed in such a manner that a height of the gasket which is a length in a depth direction of the gasket becomes greater than the depth of the groove and a protruded length of the two protruded parts becomes equal to or more than a difference between the height of the gasket and the depth of the groove. <P>COPYRIGHT: (C)2013,JPO&INPIT |
