第１ノ位置、ｒＳＴＡＲＴＪは第３の位置を示す。Figures 1 to 6 show one embodiment of the present invention, in which Figure 1 is a longitudinal sectional side view, Figure 2 is a longitudinal sectional view at the "LOCKJ" position, Figure 3 is a front view, and Figure 4 is a longitudinal sectional view. TV-I in Figure 1
5 and 6 are views corresponding to FIG. 2 at different positions, and FIG. 7 is a view corresponding to FIG. 1 showing another embodiment of the present invention. In the drawings, 1 is a cylinder case, 2 is a lock groove, 3 is a rotor, 4 is a lock plate, 4b is one tip, 4c is the other tip, 6 is a key hole, 7 is a key, and rLOCKL is the first hole. The position rSTARTJ indicates the third position.

Claims

[Scope of utility model registration request]

A rotor having a key hole, which is movably provided in the rotor, and is normally biased such that one tip thereof protrudes from the outer periphery of the rotor, and when a regular key is inserted into the key hole. a lock plate that is flush with the outer periphery of the rotor, a cylinder case into which the rotor is rotatably inserted, and a state in which the rotor is located at a first position provided on the inner periphery of the cylinder case. and a pair of lock grooves for restricting rotation of the rotor with respect to the cylinder case by the lock plate being enlarged when the key is removed from the key hole or when a key different from the original key is inserted. , a second rotor provided on the inner periphery of the cylinder case, in which a regular key is inserted into the rotor and the rotor is rotated by a predetermined angle in one direction from the first position;
and a third position further rotated by a predetermined angle in one direction to form a gap with the other end of the lock plate, and the key is manually operated in the third position. a cylinder lock, comprising spring means which is arranged to be actuated when the lock is released, and which rotates the rotor together with the key toward a second position.
