端は外側外筒21の開放端から突出し、その突出部分とシ
ャフト23との間にブーツ25が取付けられる。The outer cylinder of this joint has a triple structure in which a vibration-proof material 22 such as rubber is interposed between the inner outer cylinder 20 and the outer outer cylinder 21.
In the case shown in the figure, a tripod member 24 connected to a shaft 23 is inserted into the inside of the inner outer cylinder 20 to constitute a so-called tripod constant velocity joint. The open end of the inner outer cylinder 20 protrudes from the open end of the outer outer cylinder 21, and a boot 25 is mounted between the protruding portion and the shaft 23.
内側外筒20は、３等分位置に軸方向の３本のトラック
溝26を有し、各トラック溝26相互間に内壁面27が形成さ
れ、全体としてクローバ形になっている。The inner outer tube 20 has three track grooves 26 in the axial direction at three equally spaced positions, and an inner wall surface 27 is formed between the track grooves 26 to form a clover shape as a whole.
また、外側外筒21の内面も内側外筒20の外周面に沿っ
たクローバ形をなす。従って外側外筒21の内周壁には、
トラック溝26に沿った形状のトラック対応溝28が形成さ
れ、各トラック対向溝28の相互間に内壁間27に沿った形
状の内壁対応面29が形成される。The inner surface of the outer cylinder 21 also has a clover shape along the outer peripheral surface of the inner cylinder 20. Therefore, on the inner peripheral wall of the outer outer cylinder 21,
