PROBLEM TO BE SOLVED: To provide a pressure discharge structure of a switch capable of preventing breakage of a mounting bracket due to a fastening member during internal pressure rise of the switch, and of preventing dispersal of the fastening member and that of incorporated materials of the switch. SOLUTION: A cushioning washer 50 is penetratingly attached to a bolt 41 piercing both a mounting plate 15 of the switch and the mounting bracket 40. The cushioning washer 50 is provided with a lock part 50b engaging with the mounting bracket 40 (40T) to restrict the movement of the bolt 41 when a lid body 14 is deformed by the internal pressure rise of the switch to separate it from its opening.
