The elastic member is disposed between a case and the weight. The weight has a rectangular shape having long sides in a first direction and short sides in a second direction in top view, the first direction being orthogonal to an up-down direction, the second direction being orthogonal to the up-down direction and the first direction. The damper member is disposed between the case and the elastic member. The damper member contacts the elastic member when the vibrating body is in a stationary state.
