Claim 0:
1. A parking actuator connected to a brake actuator that performs braking of a vehicle, the parking actuator comprising:
a parking gear connected to the brake actuator to be rotatable together;
a parking lever having one side hingedly fixed and the other side engaged with the parking gear;
a parking motor provided to generate power;
a power conversion unit comprising a spindle member rotating by receiving a rotational driving force of the parking motor and a nut member screwed to the spindle member to move forward or backward; and
a pressing unit installed on the nut member to press the parking lever by the nut member moved forward or backward,
wherein a rotation shaft of the parking motor is arranged to be substantially parallel to a rotation axis of the parking gear,
wherein the pressing unit comprises a pressing member provided to penetrate through an end of the nut member to be movable relative to the nut member and to press the parking lever; and an elastic member interposed between the pressing member and the nut member to elastically support the pressing member,
wherein the nut member includes a nut body having a female thread engaged with a male thread formed on an outer circumferential surface of the spindle member; and a pin extending in a longitudinal direction from the nut body so that the pressing unit is installed,
wherein the parking lever includes a pressing surface in close contact with the pressing member and a stepped surface formed to be stepped on the pressing surface, and
wherein the stepped surface is provided on an extension line in advancing and retreating direction of the nut member to prevent the advancing movement of the nut member by coming into contact with an end of the pin.
