A rotation angle detection device of the present disclosure includes, a rotating body having a cylinder and configured to rotate with rotation of a rotating shaft coupled to an inside of the cylinder, an engagement protrusion provided inside of the cylinder of the rotating body and protruding in a first direction serving as a direction in which the rotating shaft extends, an elastic member mounted to the engagement protrusion and having an elastic holding part, a case having a rotation supporting part that rotatably supports the rotating body, and a rotation angle detector configured to detect a rotation angle of the rotating body. A predetermined gap is provided between the rotation supporting part of the case and an outer periphery of the cylinder of the rotating body. A fitting part protruding in a second direction perpendicular to the first direction is formed on an outer periphery of the engagement protrusion. The elastic member is mounted to the engagement protrusion so that the elastic holding part can be elastically deformed in a rotating direction of the fitting part.

In a touch sensor unit, a bracket body is provided with a first protruding portion which is disposed on a vehicle interior side of a base portion, a gap portion is provided between the first protruding portion and the base portion, the height from the bracket body to the distal end of the first protruding portion is smaller than the height from the bracket body to the sensor portion. Therefore, when the sensor portion and the base portion are elastically deformed by contact with a blockage, the elastically deformed sensor portion and base portion enter the gap portion, thereby preventing the sensor portion and the base portion from being pressed against the corner portion of the bracket without increasing the rigidity of the sensor portion and the base portion.
