SUSPENSION LOCK MECHANISM OF VEHICLE

To provide a suspension lock mechanism of a vehicle that can stop a stroke of a suspension. In a suspension lock mechanism (430) of a rocking vehicle where a pivot arm (402) is rockably supported by a support arm (36b) provided on the vehicle body side via a spindle (332), a front wheel is supported by an end of the pivot arm (402) via an axle and a stroke of a link type suspension mechanism as a suspension in which a shock absorber is extended/contracted by a rocking of the pivot arm (402) is stopped, a cylindrical drum (441) is provided to the pivot arm (402) with the drum encircling the spindle (332) and the rocking of the pivot arm (402) can be locked by providing a band shoe (442) that stops the turning of the drum by frictional force to the support arm (36b).
