Abstract
The present invention is provided to prevent intrusion of dust, moisture, and the like, and simulatively deliver a kinetic operation feeling in response to an operation of an operator, and generate vibrations as necessary and separately from the operation of the operator. There is provided an inertial force imparting device including a stator, a mover that is arranged to be movable relative to the stator in a movable direction, a weight attached to the mover, an actuator unit that includes a shape memory alloy wire provided between the stator and the mover, instantaneously displaces the mover in the movable direction, and delivers an inertial force to the outside based on the displacement, and an elastic member that biases the mover toward the stator side along the movable direction, in which the shape memory alloy wire changes in length according to temperature, and changes the interval between the mover and the stator by expansion and contraction according to energization heating.
