To provide a clutch apparatus capable of forming a four-system oil passage without increasing the diameter of an input shaft and the length of the shaft.

The clutch device includes the input shaft 20 having a hole 20a formed from the end in the axial direction, a cylindrical stator shaft 18 disposed on the outer circumference of the input shaft 20, and a cylindrical sleeve 11a disposed on the outer circumference of the stator shaft 18. The stator shaft 18 has an internal oil passage (a groove 18d). A gap formed between the inner peripheral surface of the sleeve 11a and the outer peripheral surface of the stator shaft 18 is a first oil passage 31, the internal oil passage (the groove 18d) is a second oil passage 32, a gap formed between the inner peripheral surface of the stator shaft 18 and the outer peripheral surface of the input shaft 20 is a third oil passage 33, and the hole 20a of the input shaft 20 is a fourth oil passage 34.
