PURPOSE:To facilitate intrusion of small balls into the inner rotor of an equal speed joint by pivoting swingingly an oscillative frame equipped with a detent piece, which shall be in detention with the inner rotor, and thereby allowing the inner rotor to make oscillative swing with respect to the outer rotor. CONSTITUTION:When working fluid is introduced into the working cylinder 96 from a fluid supply/exhaust hole 99, a rod 98 expands and sinks together with a framing 101, and then a detent piece 106 is fitted in a coupling hole provided in the inner rotor of an equal speed joint. Then the working fluid is introduced into a cylinder 108 to allow a rod 110 to sink, and this motion is converted into rotation of a gear 116 through a link 113 and an arm 117, and thus the detent piece 106 swings round the swing center line of the swinging shafts 104, 105. Accordingly, the inner rotor is put in oscillative swing to permit easy intrusion of balls in the holes on the side exposed from the outer rotor. |
