Any cylinder lock such as a magnetic tumbler lock or a disc tumbler lock can be used.

At the inner end of the inner cylinder of the first cylinder lock 21 in the axial direction, the base end of the sickle 3 whose end is disengaged from the engaging hole 50 of the receiving box 10 or other engaging portion 50 is fixed. Has been done. In addition, reference numeral 25 in the drawing indicates a pressing plate of the sickle 3.

This sickle 3 is locked by the first key 23 when locked.
For example, in FIG. 3, the door 20 of the receiving box 10 is locked by rotating 90 degrees clockwise and engaging the notch formed at the tip thereof with the locking portion 50 of the receiving box 10.

Further, as shown in FIG. 3, on the inner end surface of the outer cylinder 27 of the first cylinder lock 21 in the axial direction, a projecting piece 28 integral with the projecting piece 28 projects rearward, and the projecting piece 28 is a sickle. 3 is fitted in an arcuate hole 31 provided at the base end portion of 3.

The set of the projecting piece 28 and the arcuate hole 31 serves as a stopper for restricting the rotation range of the sickle 3 which rotates together with the inner cylinder of the first cylinder lock 21.

Reference numeral 4 is a control lever pivotally attached to the inner surface of the base frame 1 via a fixed guide piece 13 having a U-shape, and a bent tip end portion of the control lever 4 is It selectively engages with the base end of the sickle 3 in the unlocked position (see FIG. 3) to restrain (prevent) the displacement of the sickle 3 toward the locked position.
