Clutch assembly

A clutch assembly comprising:

• a clutch and a damper device housed in a housing that is connected to an engine output member, said clutch having a first friction member and a second friction member,
• an output member connected to an input shaft of an automatic transmission and having both sides directly supported on the housing via a bearing, and
• a take-off controller that transmits an output of the engine to the automatic transmission by engaging the clutch so as to start a vehicle, wherein,
• the damper device includes a drive plate connected to an output member of the clutch, a driven plate connected to the output member, a first spring functioning in a serial manner between the drive plate and the driven plate, and a second spring functioning between the drive plate and the driven plate with a predetermined allowance, and the first spring is disposed at an inner radial side of the damper device with respect to the second spring;
• and
• one of the first and the second springs being arranged in the radial direction so as to be aligned with the first and second friction members in an axial direction,
• wherein:
• the input shaft of the transmission is engaged with an inner peripheral surface of the output member with a spline;
• a sleeve shaft is fit with the input shaft with a first gap so as to be fit with the output member oil tightly;
• a hub constituting the housing is oil tightly and rotatively supported on a transmission case of the transmission with a second gap formed on an outer radial side of the sleeve shaft;
• and
• the first gap and the second gap form a lubricating oil circulation passage in the housing.
