る。According to the third aspect of the present invention, the fastening direction of the bolt fixing the sensor and the heat shield cover together is orthogonal to the fastening direction of the fastening bolt connecting the transmission housing to the engine, and the heat shield cover is extended. Since the projecting portion is arranged close to the head surface of the fastening bolt, even if the sensor and the heat shield cover are fastened and fixed at one point, the extending portion is engaged with the head surface of the fastening bolt. The sensor and the heat shield cover can be prevented from rotating, and therefore, the detachment workability can be improved by the one-point stop of the sensor and the heat shield cover and a reliable fixing can be achieved without adopting a special rotation stop structure. it can.
