<P>PROBLEM TO BE SOLVED: To simplify the structure of a power transmission mechanism installed between a drive side first shaft and a driven side second shaft without lowering a power transmission efficiency. <P>SOLUTION: This power transmission mechanism 10 is installed between the motor part M side first shaft 6 and the second shaft 9 in which a worm meshing with a worm wheel 11 is engraved. The power transmission mechanism 10 is so formed that power transmission from the first shaft 6 to the second shaft 9 is allowed in both forward and backward directions but the power transmission from the second shaft 9 to the first shaft 6 is allowed in either of the forward or backward directions. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
