<p>PROBLEM TO BE SOLVED: To provide a mechanism for reducing the occurrence of abnormal noise, when releasing depression of a push button part, with a simple structure, without causing up-sizing of the push button part of a push button device in the depression direction.SOLUTION: The push button device includes a support member 11 having an opening 11a, a push button part 12a having an operation surface exposed to the outside when being fitted in the opening 11a, and a biasing member 12b for biasing the push button part 12a in a direction opposite from the depression direction. The support member 11 has an abutting portion 11d against which the push button part 12a abuts, while being biased by the biasing member 12b, thus positioning the push button part 12a at the initial position. A surface 12f of the push button part 12a abutting against the abutting portion 11d is formed while inclining in the depression direction.</p> |
