困難となる不具合があつた。 FIGS. 2a and 2b show the cross-sectional structure of the conventional spline structure shown in FIG. Although this is easy, abrasion particles of the clutch assembly 6 and rust due to fretting corrosion can easily enter between the splines 4 and 10 and cause clogging, which can cause poor clutch disengagement.According to b. Since the abrasion particles and rust escape between the tooth top surface 12 of the outer spline 4 and the tooth bottom surface 14 of the inner spline 10, no clutch disengagement occurs, but the wear of the tooth surfaces causes the clutch shaft 2 and clutch hub 8 to There was a problem that made centering difficult.

る。 The present invention was proposed in view of the above, and includes a spline structure capable of transmitting power consisting of an internal spline of a clutch hub and an external spline of a clutch shaft that fit into each other. An annular groove or a connected screw groove is carved on one side at right angles to the axis center line,
The spline structure is characterized in that foreign matter existing on the axial sliding surfaces of both the inner and outer splines is configured to collect in the annular groove or threaded groove.

２の歯先２４に形成しても同様である。 Although the annular grooves 20, 20... in the above embodiments were explained as annular thin grooves, the annular grooves 20, 20, .
It is also possible to use a wide trapezoidal groove 20 as in the modified example shown in FIG. Also, inner spline 2
The same is true when forming the tooth tip 24 on the second tooth tip 24.

様の作用効果を奏する。 FIG. 6 shows a second modification of the above-mentioned embodiment, in which a groove 2 is formed in the tooth tip 18 of the outer spline 16 along the axis center line.
8 is formed, and an annular groove 30 or a threaded groove is further formed on the tooth tip 18. FIG.
In addition, an annular groove 30 or a threaded groove is formed, and each modification also provides the same effects as the above embodiment.
