PROBLEM TO BE SOLVED: To provide a cylinder lock capable of ensuring high waterproofness.SOLUTION: A cylinder lock 1 comprises: a cylinder 4 provided with a key insertion hole into which a key is inserted and a plurality of tumblers 5 held so as to be movable forwards and backwards in a radial direction, the tumblers entering the inside of the cylinder 4 and becoming rotatable by inserting a normal key into the key insertion hole; and a substantially cylindrical holder 2 for storing the cylinder 4 in its inside. The holder 2 is divided into a first holder part 2A and a second holder part 2B by a dividing plane 2a in the longitudinal direction, junction surfaces 2d, 2g perpendicular to the dividing plane 2a are respectively formed at least in ranges of the first holder part 2A and the second holder part 2B where the tumblers 5 are arranged, and the junction surfaces 2d, 2g are overlapped on each other in the vertical direction (radial direction). |
