[0002]

2. Description of the Related Art An inner cylinder is rotatably mounted on a shaft cylinder portion of a fixed case fixed to a door so as to be rotatable and immovable back and forth, and a locking member of the door with respect to a fixed frame body is connected to a rear surface of the inner cylinder. A lock unit that inserts the handle shaft into the inner cylinder so that it cannot rotate and slides back and forth, biases the handle forward by a spring, and restrains the handle from being forwarded by a locking mechanism that is interlocked with the rotor. A pop-out type lock handle device provided on a handle shaft is already known.

When a pop-out type lock handle device is used for a door of a vending machine or the like in which a relatively large amount of money is always stored, a lock unit is exposed to an attack by illegal unlocking by a picking tool or violent destruction by a drill tool or the like. However, no matter how complicated the internal locking mechanism is, the internal structure will be elucidated by criminal groups sooner or later, so the durability of the crime prevention effect cannot be expected much. It has also been proposed to embed a hard metal material that is strong against a drill tool in the lock unit, but its effect is limited.

[0004]
