PROBLEM TO BE SOLVED: To provide a compact and stout padlock having a counter for the number of times of unlocking.SOLUTION: A padlock 1 includes a lock body 2, a shackle 3, a cylinder lock 4 arranged in the lock body 2, a latch member 5, a counter dial 6, and a transmission mechanism 7. Locking is completed by putting the shackle 3 on a member to be locked, rotating a rotor 42 with a key to a locking direction in the situation in which the shackle 3 is pushed into a receded position as a locked position, engaging a latch portion 51b with a notch 33 of the shackle 3, and thereafter taking out the key from the rotor 42. When unlocked, the latch member 5 and a holding member 71 rotate together with the rotor 42 to an unlocking direction, and the counter dial 6 is rotated through a shaft member 72 and a ratchet claw member 73 so as to increment a displayed numerical value.SELECTED DRAWING: Figure 2 |
