ABSTRACT:
A padlock includes a lock base formed with first and second shackle insert holes, a lock receiving space which is disposed between the first and second shackle insert holes and which has an upper section communicated with the second shackle insert hole, and a ball chamber which extends transversely between the first shackle insert hole and the upper section of the lock receiving space. A lock device is received in the lock receiving space, and has an axially rotatable key-operated lock core which is provided with a plunger formed with a latch projection. A locking unit includes at least one ball member rollingly disposed in the ball chamber adjacent to the plunger. A shackle has longer and shorter leg portions to be received in the first and second shackle insert holes, respectively. The shorter leg portion is formed with a plunger engaging groove for engaging the latch projection of the plunger. The longer leg portion is formed with a ball retaining groove for engaging the locking unit. A biasing spring is disposed in the first shackle insert hole for biasing the longer leg portion upwardly.
