Abstract
Abstract A parking brake device adapted to be attached to a vehicle including a clutch lever on a handlebar such as a three- or four-wheeled buggy, wherein a parking brake is arranged coaxially with respect to the clutch lever; a lock arm is provided, which is formed at its free end with a lock hole for holding a parking brake lever in its braking position; and upper and lower pins are respectively inserted into upper and lower pin holders of a slitted sleeve mounted on the parking brake lever. The upper pin is pushed to engage the lower pin with the clutch lever and rotate therewith the parking brake lever by manipulation of the clutch lever, so that the slit on the parking brake lever is advanced into the free end of the lock arm to hold the parking brake in its braking position by the upper pin fitted into the lock hole in the lock arm.
