Patent ID: 8400033

Claim:
An unlocking actuator comprising: a rotary gear configured to rotate by which rotary torque generated by an electric motor in order to unlock a vehicle seat is transmitted through rotary torque transmission means; a pulley in which a substantially sectorial insertion hole is formed along a rotational direction and an abutting surface is formed on one end side of the insertion hole; a first inner cable having one end fixed to a first groove for winding formed in an outer circumferential part of said pulley and wound in said first groove for winding, and another end connected with an unlocking mechanism; and a second inner cable having one end fitted idly in a second groove for winding formed in said outer circumferential part of said pulley and wound in said second groove for winding, and another end connected with an unlocking operation rod; wherein said rotary gear is provided in a position which corresponds with said insertion hole, has an opposite surface against said abutting surface of said pulley, and provides a projecting portion rotating inside said insertion hole; and wherein said pulley is configured to unlock a lock when said rotary torque is transmitted to said rotary gear and said opposite surface abuts said abutting surface by rotating with said rotary gear and wind said first inner cable around said pulley to activate said unlocking mechanism, and is configured to unlock said lock by rotating when said second inner cable is pulled to a side of said unlocking operation rod by operation of said unlocking operation rod and wind said first inner cable around said pulley to activate said unlock mechanism.
