Claims

[Claims for Utility Model Registration] 1. A body, and a plurality of tumbler insertion holes which are rotatably fitted into the body and have a key insertion hole at the center in the axial direction, and which are orthogonal to the key insertion hole. a rotor, a tumbler that is inserted into a tumbler insertion hole of the rotor and is urged by a spring to engage with a locking groove provided in the body; In the cylinder lock, the tumbler is formed into a pair of left and right half tumblers that are inserted into the tumbler insertion hole, and each half tumbler has the guide groove. A cylinder lock characterized by having engaging protrusions that engage each groove separately. 2. A protrusion extending in the key insertion direction is provided at the center of the side surface of the key insertion hole, and the rear end reference surface of the protrusion is brought into contact with the rear end orthogonal surface of the key side guide groove to form a pitch between the key thread and the tumbler. 2. The cylinder lock according to claim 1, wherein the cylinder locks are aligned. 3 a pair of sliding grooves separating the tumbler insertion hole by a guide wall formed in the key insertion hole;
The cylinder lock according to claim 1, which is a registered utility model, characterized in that the sliding groove is formed with a communicating groove that communicates with one end of the sliding groove. 4. The cylinder lock according to claim 1, wherein a groove extending in the vertical direction is formed on both sides of the sliding groove.
