<p>PURPOSE:To minimize the size of a structure and make power transmission ever so smooth, by linking up a convex part on the outer surface of an inner ring member with another convex part on the inner surface of an outer ring member via an elastic member, in case of a coupling between both ring members of a joint part. CONSTITUTION:Two convex parts 13 are set up on the inner surface of an outer ring member 12 while two other convex parts 16 are set up on the outer surface of an inner ring member 15 as well. And, as for inner and outer ring members 12 and 15, the inner one 15 is inserted into the outer one 12 so as to cause an elastic member 18 to be interposed between each of convex parts 13 and 16 in the direction of rotation, and a flange 17 is loosely fitted in the inner surface of the outer ring member 12. Then, a chamfer 14 of the outer ring member 12 is fitted in a slit 6A of a cam shaft 6 and the inner ring member 15 is secured to a pump shaft (not illustrated herein). With this, power transmission to the inner ring member 15 takes place through these convex parts 13 and 16 having interposed the rubber damper 18 from the outer ring member 12 so that smooth power transmission is carried out in order.</p> |
