、（２）は−線に揃う。Since the tip of the first joint (1) is a spherical or tapered convergent tip (1b) or a small diameter shaft portion (1d) with a predetermined outer diameter, initially, the first and second joints (1) , (2) are slightly deviated and/or crossed, the joint (1) can be initially fitted into the front shaft hole (21) without any problem. Following this initial fitting, when the part following the convergent tip (1b) or the small diameter shaft (1d) enters the front shaft hole (21), the front shaft hole (21) is inserted into the joint (1). Since the inner diameter corresponds to the outer diameter, the fitting (1)

前部軸穴（２１）がパイロット部（２３）の誘導作用を
効果的ならしめることも明白である。The ease and smoothness of the spline (1a) in the spline shaft hole (2a) is determined by the fact that the tip of the joint (1) is spherical,
A tapered one is the best, and one with a convergently chamfered base and a small diameter shaft portion with a predetermined outer diameter in the remainder is second to the first two. By the way,
If the second joint (2) is of a conventional spline shaft hole, the latter type is the spline (1) of the joint (1).
The allowable degree of deviation between 1a) and the spline groove of the joint (2) is more restricted than the former two types. It is clear from the above description that this point is covered by the pilot part (23) of the second joint (2). and,
It is also clear that the front shaft hole (21) makes the guiding action of the pilot part (23) effective.
