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.

Door handle apparatus

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.

Door handle apparatus and controller

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.

Input device

A gas fuel injection valve is provided in which a single nozzle member () is fixedly provided in a front end part of a valve housing (), and this nozzle member () has formed therein a valve seat (), a valve hole () extending through a central part of the valve seat (), a throttle hole () having a smaller diameter than that of the valve hole () and communicating with an outlet of the valve hole (), and a nozzle hole () having a larger diameter than that of the throttle hole () and communicating with an outlet of the throttle hole (), wherein when an internal diameter of the throttle hole () is D, a length of the hole () is L, an internal diameter of the nozzle hole () is D, and a length of the nozzle hole () is L1/1&#x3e;1&#x2003;&#x2003;(1)1&#x3c;2/1&#x2267;1.2&#x2003;&#x2003;(2)the above expressions (1) and (2) are satisfied. Thus, it is possible to provide a silent gas fuel injection valve by preventing a gas fuel flow, separation phenomenon at the boundary between the throttle hole and the nozzle hole.
