Abstract

Provided are a gasket and a sealing structure which are capable of exhibiting stable sealing performance, even under conditions in which the temperature of the usage environment is high. This gasket (100) seals a gap between a first member (200) and a second member (300) as a result of being inserted into an annular insertion groove (210) provided in the first member (200), and being disposed in close contact with the groove bottom surface (211) of the insertion groove (210) and an end surface (310) of the second member (300) respectively. The gasket (100) is characterized by being designed such that, under the maximum temperature of the usage environment, the circumference of the outer peripheral surface (130) of the gasket (100) is equal to or less than the circumference of a side-wall surface (212) of the insertion groove (210) at the outer peripheral side.

Description

technical field [0001] The invention relates to a sealing ring and a sealing structure for sealing a gap between two components. Background technique [0002] In inverters or inverters mounted in hybrid vehicles (HV), electric vehicles (EV), fuel cell vehicles (FCV), etc., a waterproof seal is provided between the case body and the cover. That is, by installing a sealing ring in the annular mounting groove of one part of these housing body and cover body, and making the sealing ring close to the groove bottom surface of the mounting groove and the end surface of the other part, the housing body and the cover are sealed. gap between bodies. Moreover, these housing bodies or covers are mostly made of aluminum die-casting. Generally, the dimensional accuracy of aluminum die castings is not too high. In this case, by making the cross-sectional shape of the seal ring longer in the longitudinal direction than in the lateral direction, even if the error in the amount of compress...
