<P>PROBLEM TO BE SOLVED: To provide a simple compact joint mechanism for providing a shaft inside a rotatable pipe to which the shaft is nonrotatable and for making the shaft move in the axial direction. <P>SOLUTION: This joint mechanism is employed for making the shaft, which is provided inside the rotatable pipe and nonrotatable to the pipe, move in the axial direction. It includes: a shaft end part, which has a step provided at the top of the shaft; a first locking piece, which is fitted to this shaft end part and locked by the step to lock and support one end of the inner ring of a bearing passing a slit provided on the pipe; a second locking piece, which is basically of the same shape with the first locking piece and locks and support the other end of the inner ring of the bearing; a stopper ring, which is fitted into the shaft end part and prevents the first and second locking pieces from moving in the axial direction; and the outer ring of the bearing, which is fitted to the inner ring of the bearing. <P>COPYRIGHT: (C)2009,JPO&INPIT |
