<P>PROBLEM TO BE SOLVED: To provide a drive unit having uniform reliability of torque transmission, in which piston housings arranged in parallel can be easily and quickly assembled (Montage) and dissembled (Demontage). <P>SOLUTION: A piston rod is formed in one body, and an eccentric part can be raised on a drive shaft and can be fixed to the drive shaft. The eccentric part is configured for a grip joint part that can be manufactured in an assembled state with the drive shaft. Each piston having the piston rod, the eccentric part and a fixing means can be disposed in a piston housing via an attaching hole provided in an axial direction of the piston for the grip joint part. The grip joint part can be manufactured after attaching the drive shaft via the attaching hole. <P>COPYRIGHT: (C)2012,JPO&INPIT |
