<P>PROBLEM TO BE SOLVED: To provide a yoke shaft joint structure capable of improving assembling workability, preventing an error in assembling a bolt and suppressing the protruded amount of the bolt after fastened. <P>SOLUTION: In the yoke shaft joint structure, in such a temporarily assembled state that the bolt 60 is inserted through a bolt hole 51 of a yoke member 30 and threaded to a temporarily assembled nut 70 with the front end of a small-diameter screw portion 61 of the bolt 60 being threaded into a screw hole 52, a shaft 12 can be inserted into a yoke member 30 with the small-diameter screw portion 61 facing a shaft insertion hole 30a of the yoke member 30. During final assembly, the bolt 60 is fastened and turned to move a bolt 30 to the front end side of the temporarily assembled nut 70, and the temporarily assembled nut 70 is turned to be moved to the front end side of the screw hole 52 until a large-diameter screw portion 62 of the bolt 60 is threaded to the screw hole 52. Thus, the bolt 60 can be fastened to the yoke member 30. <P>COPYRIGHT: (C)2008,JPO&INPIT |
