PROBLEM TO BE SOLVED: To achieve miniaturization of a cylinder lock having a keyhole provided in an eccentric position in an inner cylinder.SOLUTION: A cylinder lock 1 includes: an inner cylinder 11 in which a keyhole 16 subject to insertion/removal of a key XA1 is provided in an eccentric position; a pair of shutter members 19 and 20 which are opened when the key XA1 is inserted into the keyhole 16 and which close the keyhole 16 by being closed when the key XA1 is removed from the keyhole 16; coil springs 21 and 22 which apply closing-direction power to the shutter members 19 and 20; and guide grooves 18f, 18g, 18h and 18i, and guide projections 19a, 19b, 20a and 20b, which guide the shutter members 19 and 20 in a direction obliquely crossing a direction connecting the center of the inner cylinder 11 and the center of the keyhole 16. |
