Claims

[Claims for Utility Model Registration] (1) A rotor case, a rotor rotatably mounted within the rotor case, a key insertion hole formed along the rotation axis of the rotor, and the key A plurality of tumblers are installed at predetermined intervals along the insertion hole, and the tumblers are normally held in a locked position protruding from the rotor to prevent rotation of the rotor, and a predetermined key is inserted into the key insertion hole. In a cylinder lock which, when inserted, engages with the notch and moves and is settled in an unlocked position within the rotor to allow rotation of the rotor, the tumbler is moved at a cross-sectional position intersecting the rotational axis of the rotor, A cylinder lock characterized by having a plurality of cylinder locks protruding from the rotor at different positions. (2) In paragraph 1 of the claims for utility model registration,
A cylinder lock in which the tumbler is a disc tumbler that moves in a direction that is approximately perpendicular to the rotational axis of the rotor. (3) In paragraph 1 of the claims for utility model registration,
A cylinder lock in which a tumbler at a cross-sectional position intersecting the rotational axis of the rotor engages with a notch of a key inserted into a key insertion hole and is movable in the same direction. (4) In paragraph 1 of the claims for utility model registration,
A cylinder lock in which a tumbler at a cross-sectional position intersecting the rotor's rotational axis engages with a notch of a key inserted into a key insertion hole and is movable in opposite directions. (5) In paragraph 4 of claims for utility model registration,
The key has one row of notches and a row of notches formed rotationally symmetrically with the one row of notches about an axis of the key, and each tumbler is formed to be engageable with one row of notches. cylinder lock. (6) In paragraph 3 of claims for utility model registration,
the key has two rows of notches arranged side by side in different steps;
A cylinder lock in which each tumbler is capable of engaging with one row of notches. (7) In paragraph 4 of claims for utility model registration,
The key has two rows of notches arranged side by side in different steps, and two rows of notches formed rotationally symmetrically about the two rows of notches and the axis of the key, and each tumbler has
A cylinder lock that is formed so that it can be engaged with two rows of notches.
