Problems solved by technology
That is, in order to ensure the operating range of the slider, the size of the protection device becomes large
In addition, since the cover plate is rotationally moved to the open position when the magnet lock (lock device) is opened with a magnet key, the structure of the protection device is complicated.

Embodiment Construction
[0039] Exemplary embodiments of the present invention are described with reference to the drawings.
[0040] A cylinder lock protection device according to an exemplary embodiment is a device provided on an upper side of a key hole of a cylinder lock that is assembled in a two-wheeled vehicle. According to this cylinder lock protector, the key hole can be opened and closed from the outside, so that the cylinder lock can be protected. Such as Figure 1 to Figure 4 As shown, the cylindrical lock protection device mainly includes: a housing 1, which has a housing 1a and a cover 1b; a cover plate 2; a torsion spring 3, which is used as a pushing device; a lock device 4, which constitutes a magnet lock; a magnet key MK ( See figure 2 ), which serves as the opening device; and the button 5, which serves as the operating device.
[0041] Such as figure 2 As shown, a housing 1a made by die-casting moldings includes not only an insertion hole 1aa, but also a magnet lock protrusio...

Description
technical field [0001] The present invention relates to a cylinder lock protector capable of preventing damage to a cylinder lock assembled in a two-wheeled vehicle or the like. Background technique [0002] Conventionally, there has been proposed a cylinder lock protector for preventing an unauthorized person from prying open or destroying a cylinder lock mounted on a two-wheeled vehicle or the like by inserting scissors, a screwdriver, etc. into a keyhole of the cylinder lock (For example, see JP-A-2003-239581). This type of guard consists of a cover that can be rotated from a closed position where the keyhole is covered to an open position where the keyhole is open and a torsion spring that urges the cover from the open position to the closed position a button for holding the cover in the open position; a magnet lock for locking the cover to keep the cover in the closed position to block the keyhole; and a magnet key for using the magnetic force of the magnet to Release...
