<P>PROBLEM TO BE SOLVED: To provide a gear change power transmission structure of an on-vehicle power unit such that the flexibility of a fitting motor of a gear change motor is large and that even a member at a circumference of the change gear motor is easily laid out at an optimum position. <P>SOLUTION: There is provided the gear change power transmission structure of the on-vehicle power unit such that in an on-vehicle power unit (P) configured to carry out switching of a plurality of change gear means of a change gear device (50) in prescribed timing as a change gear operation mechanism (70) is driven when a change gear motor (100) is driven and a shift spindle (55) is rotated by a change gear power transmission mechanism (110), a change gear power transmission case (102) which houses the change gear power transmission mechanism (110) is fitted to a unit case (20) by inserting a part of the shift spindle (55) into the change gear power transmission case (102), and the change gear motor (100) is held by the change gear power transmission case (102) by inserting a motor driving shaft (100a) into the change gear power transmission case (102). <P>COPYRIGHT: (C)2012,JPO&INPIT |
