Abstract:
A parking brake assembly for a small-sized vehicle, comprising;a first support shaft; a support member, a parking brake lever swingably supported on the support member by the first support shaft, the parking brake lever being operated from a brake releasing position to a brake operating position by a driver for braking, a first resilient biasing means for biasing the parking brake lever toward the brake releasing position, a second support shaft, a lever locking member swingably supported on the support member by the second support shaft, the locking member being swung to a locking position of locking the parking brake lever at the brake operating position for braking, and operated from the locking position toward an unlocking position by the driver for releasing the braking, a second resilient biasing means for biasing the lever locking member toward the locking position, a first engage portion on the parking brake lever, and a second engage portion on the lever lock member for being brought into engagement with the first engage portion of the parking brake lever, wherein when the parking brake lever is moved from the brake releasing position to the brake operating position for braking, the lever locking member is swung from the unlocking position to the locking position by the resilient force of the second resilient biasing means while following the parking brake lever moving to the brake operating position, whereby the first engage portion of the parking brake lever is brought into engagement with the second engage portion of the lever locking member swung to the locking position to lock the parking brake lever at the brake operating position, and wherein when the lever locking member is moved against the resilient force of the second resilient biasing means from the locking position to the unlocking position for releasing the braking, the second engage portion of the lever locking member is disengaged from the first engage portion of the parking brake lever, and the parking brake lever is swung from the brake operating position to the brake releasing position by the resilient force of the first resilient biasing means while being accompanied by the lever locking member.
