<P>PROBLEM TO BE SOLVED: To provide a small-sized joint 2 which prevents idle running of an output shaft. <P>SOLUTION: A 2-faced parallel recess part 11 having a plane part 12 is provided at the output shaft 2. A joint 4 is provided with a pair of arc-state crimp walls 14 for crimping an outer diameter of the output shaft 2 and a 2-faced parallel projection part 13 connecting their centers in the circumferential direction. And the 2-faced parallel projection part 13 is pressed in the 2-faced parallel recess part 11. At that time, the arc-state crimp walls 14 give guidance so that the shaft center of the joint 4 aligns with the shaft center of the output shaft 2. As an engagement face 15 having a knurling tool is formed on the 2-faced parallel projection part 13, it is firmly crimped to the 2-faced parallel recess part 11. Thus, the output shaft 2 is rotated integrally with the joint 4. <P>COPYRIGHT: (C)2003,JPO |
