Abstract: A vibration device that includes a support member, an actuator, and a sensor that detects a force applied to a vibrated member and displacement of the vibrated member in a left-right direction. The support member includes a fixing portion, a vibration portion, and an elastically deformable portion connecting the fixing portion and the vibration portion. The actuator is attached to the fixing portion and the vibration portion. The sensor is attached to the elastically deformable portion. The elastically deformable portion has a first elastic modulus in the left-right direction, a second elastic modulus in a front-rear direction, and a third elastic modulus in an up-down direction. The first elastic modulus is smaller than the second elastic modulus. The third elastic modulus is smaller than the second elastic modulus.

Abstract: A pointer includes: a pointer tip having a tip configured to point a position; a transmitter configured to emit a signal from the pointer tip; and a main body connected to the pointer tip. The main body includes: an exterior housing forming an exterior; a detector configured to detect displacement of the exterior housing and output a detection signal; and a controller configured to change an operation state of the pointer in accordance with the detection signal. The detector includes: a detection device provided on an inner surface of the exterior housing and configured to detect the displacement; and a signal outputter configured to output the detection signal in the case where the detection device detects the displacement.
