Abstract:
1. A displacement sensing device for sensing a rotational angle of a rotation of a moving member and a distance of a linear movement of the moving member, or sensing an angular velocity of the rotation of the moving member and a velocity of the linear movement of the moving member, comprising: a first movable member, which is movable together with the moving member in a direction of the linear movement by the moving member; a second movable member, which is directly engaged with the moving member to be rotatable together with the moving member by the rotation of the moving member, and which holds the first movable member so that the first movable member is rotatable together with the second movable member; a first sensor outputting a signal in accordance with the linear movement of the first movable member; and a second sensor outputting a signal in accordance with the rotation of the second movable member; a body including an opening, and accommodating the first and the second movable members therein; and a substrate which is connected electrically at least with one of the first and the second sensors, and which closes the opening.
