Abstract: A detection device provided in an interior of a vehicle door handle including an inner casing includes a base portion, a displaceable member, and a sensor. The base portion has a longitudinal shape extending along a longitudinal direction of the door handle, is disposed fixedly to the inner casing, and is configured to deform in response to a pressure applied to the inner casing. The displaceable member has a longitudinal shape extending along the longitudinal direction of the door handle and is provided to face the base portion. Either or both of one end portion and the other end portion of the displaceable member are connected to the base portion. The displaceable member includes a displaceable portion configured to be displaced relatively to the base portion in accordance with deformation of the base portion. The sensor is configured to detect displacement of the displaceable portion.

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 flame disposed on a back side of the operation panel, a pressure detector disposed between the operation panel and the flame, 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 flame or the operation panel and applies a pre-pressure to the deformation part.
