<P>PROBLEM TO BE SOLVED: To provide a shaft coupling structure allowing easy detection of an error in mounting of a shaft to a coupling. <P>SOLUTION: An insert hole 70a of a coupling 70 is furnished with a large diameter hole part (rotation admitting hole part) 70a1 in a part nearer the forefront than a bolt inserting hole 70b. Setting is made so that the relative rotation of the pinion shaft 81 with the coupling 70 is admitted with a smaller set torque than the requested torque (torque transmissible when a pinion shaft 81 is coupled with the coupling 70 in the normal position) when a bolt 71 is inserted into the hole 70b in the coupling 70 and fastened (in case of erroneous mounting) in the condition that the first coupling part 81b of the pinion shaft 81 is inserted into the large diameter hole part (rotation admitting hole part) 70a1 of the coupling 70. <P>COPYRIGHT: (C)2010,JPO&INPIT |
