Abstract
In a clutch in which an end wall of a clutch housing made of an iron and a retainer plate secured to the end wall are connected with a transmitting gear made of an iron and disposed between the end wall and the retainer plate for rotation relative to each other in the predetermined range of angle, damper springs and belleville springs for urging the transmitting gear toward the retainer plate are interposed between the end wall as well as the retainer plate and the transmitting gear, and a thrust washer is mounted to an outer surface of the end wall of the clutch housing for preventing the contact of the end wall and the belleville springs; detent bores are provided in the end wall of the clutch housing, and detent claws are formed on a thin thrust washer to be engaged into the detent bores. Thus, the relative rotation of the clutch housing and the thrust washer relative to each other is prevented, while providing a good assemblability of the clutch.
