Abstract

PURPOSE:To obtain a stable locking state by conducting locking or release between a coupler and a king pin automatically with an air cylinder. CONSTITUTION:When an air cylinder 11 pushes a lever 3 in a direction A to advance a lock section 9 into an opening 6, a spring stop pin 22 attached with a yoke 18 moves to the opposite direction A' being pulled by a spring 14. Therefore, a spring 17 latched on the spring stop pin 22 goes off, and a lock plunger stopper is released to act and is located so as to cover the rear end 21 of the lock section 9 buried in a hole, thus the lock section 9 will never go off and jump out. When the lock is to be released, the end of the spring 17 is latched on the pin 22, then the rear end 21 of the lock section 9 resumes a drawn out state without being pressed by a lock plunger stopper.
