The elastic member includes a housing connection portion that is connected to the housing, a vibrator support portion that supports the vibrator, and a spring portion that connects the housing connection portion and the vibrator support portion. The housing connection portion and the vibrator support portion are in the same plane. The spring portion is formed so as to be approximately perpendicular to the housing connection portion and the vibrator support portion.
