Abstract

A seal structure that secures sufficient sealing function even under a situation that causes a tilt of a sealing member in the seal structure. The seal structure includes a case, a cover, and a sealing member on which pressure acts while being sandwiched between the case and the cover. The sealing member includes a main body, a first protrusion protruding from the main body toward the case, and asecond protrusion protruding from the main body toward the cover. The case includes a first recess that comes into contact with the first protrusion, and the cover includes a second recess that comesinto contact with the second protrusion. The first protrusion and the first recess are different in shape. Furthermore, the second protrusion and the second recess are different in shape.

Description

technical field [0001] The present invention relates to a sealing structure including a sealing member provided with a protrusion, and to a switchgear having the sealing structure. Background technique [0002] For example, in a sealing arrangement, when two members are secured and a sealing member is sandwiched between the two members, pressure acts on the sealing member causing compression of the sealing member. This arrangement ensures a sealing function. As a related art, there is proposed a sealing structure in which a gap between two members is sealed with a gasket having a pair of curved sealing surfaces (see Japanese Patent Laid-Open No. 2006-200649). In this sealing structure, a gasket including a pair of protrusions is mounted on a mounting groove arranged in one of the two members. [0003] As described above, in the sealing structure proposed in Japanese Patent Laid-Open No. 2006-200649, the gasket is mounted on the mounting groove arranged in one of the two me...
