PURPOSE: To easily actuate a stand main unit with a rider left as aboard decreasing force for the stand main unit to rise by not grounding the stand main unit, when it is turned, but thereafter grounding a bottom end of the stand main unit with a car lowered in its height.

CONSTITUTION: When a stand main unit 12 is placed rising, a switch operates shortening an actuator 21 turning an arm 16 in a direction A. A protrusion 18 is adapted to an engaged part 19, when an arm 17 is driven in a follow-up movement to the arm 16, a link bar 25 turns a rear fork 4 in the counterclockwise direction. Thus lowering a car body in its rear part, the stand main unit 12 is grounded in its bottom end, and a rear wheel 5 is detached from the surface of the ground. When a lifter pin 39 is fitted to a recessed part 38b, a signal from a limit switch extends the actuator 21 turning the arm 16 in a direction B disengaging the protrusion 18 from the engaged part 19, and the arm 17 is made free in its turning. A rear suspension 8 is extended simultaneously with the rear fork turned in the clockwise direction, and car weight is supported to the stand main unit 12.
