Sensor mounting mechanism for a clutch case

摘要

A sensor mounting mechanism for a clutch case is provided, which can not only prevent temperature rise of a sensor but also simplify mounting of the sensor on the clutch case. The sensor mounting mechanism is for a clutch case which houses a clutch and a detection object (a pulse gear) rotating with the clutch in unison. A sensor for detecting a rotation of the detection object is inserted through a hole made on the clutch case with a thermal insulator (spacer) and a detector of the sensor is oriented opposite to the detection object.
