SUPPORT STRUCTURE FOR RAIN SENSOR

A mounting bracket is fastened to a roof header panel. The mounting bracket has an extending portion extended to a position facing a windshield. A rain sensor is engaged with the extending portion so that the rain sensor can move back and forth with respect to the windshield. A coil spring is interposed between the extending portion and the rain sensor, and a light emitting/receiving surface of the rain sensor is pushed toward the inner surface of the windshield through a silicone sheet by a biasing force from the coil spring. Since there is no need to use adhesion as a means of supporting the rain sensor, there is no need to control or inspect the quality of the adhesion.
