PURPOSE:To seek to lighten a coupling by constituting at least one hand of the input shaft side and output shaft side of a housing which partitions a working chamber out of an inner and an outer formed through pressing. CONSTITUTION:An output shaft 3 is provided with a coupling cover 11 in a body, which constitutes a housing that partitions a working chamber 27 closed at the rear along with an inner hub 7. This coupling cover 11 is constituted of an outer 13 and an inner 15 formed through steel plate pressing. The fixing of the outer 3 to the output shaft 3 is executed in such a way that the boss part 13a of the outer 13 is formed in concave-convex and this boss part 13a is engaged with a spline 3a. Accordingly, since a coupling device 37 is formed of steel plate, it is made small and light. |
