A cylinder locking device is provided in which an inner cylinder is pivotably inserted into a cylinder body, a protector is disposed opposite a rear end of the inner cylinder along an insertion direction of a mechanical key, the protector enabling the mechanical key to be inserted toward the inner cylinder, and a coil-shaped spring is provided between the protector and the inner cylinder or the cylinder body, wherein the spring (50) is formed so as to have a coil portion (50a) that extends in the axial direction of the inner cylinder (13) and a bent portion (50b) that is bent from at least one end part of the coil portion (50a) toward an interior of the coil portion (50a) in a direction along an axis of the inner cylinder (13). This enables deformation of a coil-shaped spring to be prevented.
