高価金属により成形されるのが通常である。(Prior Art and its Problems) Conventionally, this type of cylinder lock is known, for example, as described in U.S. Pat. According to this, a key hole is formed in an inner cylinder fitted coaxially into an outer cylinder, and a plate tumbler is slidably housed in a plurality of grooves penetrating the inner cylinder in the radial direction. When inserting a key, each plate tumbler engages with the end face of the key inserted into the key hole to enable the inner cylinder to rotate, thereby operating an unlocking mechanism connected to the rear end of the inner cylinder in the key insertion direction. On the other hand, when the key is extracted, each plate tumbler is pushed into the locking groove side of the outer cylinder to make it impossible to rotate the inner cylinder, that is, to prevent unauthorized unlocking. Here, since the inner cylinder needs to have a predetermined strength when the key is inserted into and removed from the key hole or rotated, the entire inner cylinder is usually made of expensive metal such as zinc.

スト減を図り難いという問題点があつた。 However, according to such a conventional structure, since the inner cylinder is integrally formed, the required total length of the cylinder lock differs depending on the type of vehicle or the mounting location. It is necessary to prepare molds for the inner cylinder, which are dominant in each case, for exclusive use, making it unsuitable for mass production and making it difficult to reduce costs.

る。(Effects of the invention) As described above, according to this invention, a keyhole is formed in the inner cylinder which is coaxially fitted into the outer cylinder so as to be rotatable around the axial direction, and the keyhole is connected to the keyhole. A plate tumbler is provided at the rear end of the inner cylinder in the key insertion direction to enable the inner cylinder to rotate when the key is inserted and to prevent the inner cylinder from rotating when the key is removed. In the cylinder lock that connects the locking mechanism, the inner cylinder is composed of a front inner cylinder part that is provided with a plate tumbler and a rear inner cylinder part that connects the unlocking mechanism, and the rear inner cylinder part and the front inner cylinder are connected to each other. Since the construction has a connecting mechanism that is rotatable and integrally connects the two parts in the axial direction, even if it becomes necessary to change the overall length of the cylinder lock due to a change in specifications, the rear inner cylinder can be easily molded using resin. It can be easily connected to the front inner cylindrical part formed in advance for common use by appropriately selecting the part. This reduces costs by eliminating the need to prepare a mold for each inner cylinder, which tends to be expensive, compared to the conventional method of molding the entire inner cylinder from metal according to its specifications. By increasing the number of parts that can be molded with resin, costs and weight can be reduced, and a dramatic increase in the mass production of cylinder locks can be expected.
