Abstract
A pressure relief valve includes a case having an opening and fixed to a surface of a housing, a cover supported by the case rotatably in a rotation direction parallel to the surface of the housing, and a first biasing member biasing the cover such that the cover rotates from a closed position to an open position in the rotation direction. The cover covers an opening of the cover in the closed position and opens the opening of the cover in the open position. The case includes a stopper engaging with the cover in the closed position. The pressure relief valve releases the engagement between the stopper and the cover when internal pressure of the housing exceeds a threshold value.
