A large number of keys 21 are projected on the outer peripheral surface of the end portion of the outer peripheral portion so that the outer peripheral surface is also radially outward, parallel to the axial direction of the male spline shaft 2 and at equal intervals in the circumferential direction. Thus, the male spline section 22 is constructed.

- a large number of key grooves 31 mated with the keys 21 of the male spline portion 22 are formed on the inner peripheral surface of the female spline shaft 3 in the radially outward direction.

Since the particle size is large and the composition does not contain any components or contains only a small amount and no force, the rattling noise can be further reduced and the sliding resistance can be further reduced. And since the sliding resistance is reduced, the feeling of tension during sliding can be alleviated.
- the average particle size of the buffer material particles B is 90% or more of the clearance C, even within the above range, in consideration of further reducing the rattling noise while preventing the axial deviation and the like.

IMPa, the buffer particles B are too soft, so even if the gap D is almost uniformly filled in the state shown in Fig. 1, the male spline shaft 2 and the female spline shaft 3 There is a possibility that the effect of reducing the rattling noise by buffering the impact due to squeezing cannot be obtained sufficiently.

- the buffer material particles B are preferably blended at a ratio of 20 to 300 parts by weight with respect to 100 parts by weight of the lubricant.
- the buffer material particle B is too small, so that the shock is absorbed by interposing the entangled portion between the two spline shafts 2 and 3, thereby causing a rattling sound.

- the lubricant composition is pushed out from the squeezing part, and the buffer particles B are also pushed out from the squeezing part at an early stage. Therefore, the effect of reducing the rattling noise may be lost at an early stage while preventing the axis line from being shifted by the buffer material particles B.
