<p><P>PROBLEM TO BE SOLVED: To provide a park lock device capable of reducing manufacturing costs. <P>SOLUTION: A park lock device comprises a base plate 1, a drive shaft 5 rotary-driven by an actuator 3, and a lock plate 7. The actuator 3 comprises a motor 13 having a projecting revolving shaft 15, a head-cut bolt 17, a nut 29, a drive body 23, and a follower body 45. The head-cut bolt 17 is connected to a tip side of the revolving shaft 15, capable of transmitting torque. The nut 29 screwed to the head-cut bolt 17 is fixed to a cam member 25 through a nut holder 29 constituting the drive body 23. In the park lock device, the drive body 23 is linearly reciprocated by linear reciprocation of the nut 29 on the rotated head-cut bolt 17. A swing body 33 constituting the follower body 45 thereby swings, and the drive shaft 5 is rotary-driven to raise or level the lock plate 7. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
