Abstract: A door handle apparatus to be attached to a door of a vehicle is provided. The door handle apparatus includes a case, a strain body, and an elastic mechanism. The case includes an outer case provided so as to face a vehicle exterior side and an inner case provided so as to face a vehicle interior side. The outer case and the inner case are integrated with each other. The strain body is provided in the case, has a sensor mounted on a middle portion between one end portion and an opposite end portion of the strain body, and the one end portion of the strain body is fixed to a portion on a center side of the inner case. The elastic mechanism uses an elastic force to press the opposite end portion of the strain body against a fixing portion at an end of the inner case.

Abstract: A door handle, to be attached to a door, includes an outer case, an inner case integrated with the outer case, and a pressure detector configured to detect pressure applied to the inner case. The inner case includes a recess in proximity to an end portion in a longitudinal direction, and the pressure detector detects a displacement of a first inner wall surface on a center portion side of the inner case in the recess, caused by the pressure applied to the inner case.

Abstract: An input device includes an operation panel, a frame disposed on a back side of the operation panel, a pressure detector disposed between the operation panel and the frame, and an elastic part. The pressure detector includes a lever including a deformation part that warps when a pressing force is applied, a protruding part provided on a first surface of the deformation part, and a surrounding wall provided on a periphery of a second surface of the deformation part; and a pressure detection element that is disposed in a region of the second surface of the deformation part surrounded by the surrounding wall, warps along with the deformation part, and outputs a pressure detection signal corresponding to the pressing force. The elastic part is disposed between the protruding part or the surrounding wall and the frame or the operation panel and applies a pre-pressure to the deformation part.
