The present invention is a cylinder lock protecting device in which a magnetic lock is provided in a casing made of a case member that is fixed in place so as to cover one end of a cylinder lock and a cover member that covers the case member from the opposite side of the cylinder lock, and a shutter plate that moves between a closed position, in which a key hole of the cylinder lock is closed when the magnetic lock is unlocked, and an opened position, in which the key hole is opened, is accommodated on the casing. The cover member (30) is made of a synthetic resin, and a metal protector (47) that is formed into a plate and interposed between the cover member (30) and the shutter plate (28) is mounted to the case member (29) so as to cover the shutter plate (28). Thus, theft prevention can be maintained while reducing the weight.
