(57) Abstract Objective Transcending proper lock cancellation stroke,The spring extends the driving force of the unlocking device onlyAs the motor burning is prevented, the rough part precision, the roughThe locking device is unlocked securely even with installation method. Constitution Locking device of automatic door and anrotsu of motor typeIn power transmission route between ku devices tensile coil spring 24By lying between, the lock of the proper locking deviceLock cancellation stroke of the power transmission route which operates cancellationThe operation stroke due to the driving force of the unlocking device transcends,te, as for driving force of unlocking device and torque of motor pullingHari coil spring 24 extending, to be absorbed, motor burningIt prevents the ke, the rough part precision, corresponds to also installation methodru.
