Claims

[Scope of utility model registration request]

spline-coupled to the first rotating shaft;
A clutch device for an automatic transmission having a clutch drum that is brought into sliding contact with a hollow second rotating shaft disposed on the outer periphery of a second rotating shaft, the first rotating shaft and the second rotating shaft being connected to each other. A first oil passage is formed between the clutch drum and a second oil passage communicating with the first oil passage, and the clutch drum has an inner peripheral surface on the side of the spline portion. The clutch drum is centered by contacting the top surface of the convex portion provided on the side of the spline portion of the first rotating shaft, and the inner circumferential surface of the clutch drum has a step lower than the surface contacting the top surface of the portion. A step-down surface is formed, and the step-down surface is in sliding contact with the outer surface of the end of the second rotating shaft, which is arranged to extend to a position near the step-down surface in the axial direction. An O-ring was disposed on the convex portion of the first rotating shaft, and a seal ring was disposed on the outer surface of the end of the second rotating shaft, and the O-ring and the seal ring were sandwiched in the axial direction. A clutch device for an automatic transmission, wherein the second oil passage is opened on an inner circumferential surface of the clutch drum.
