Problems solved by technology

[0005] However, in the case of using the light-storage chip described in the above-mentioned prior publication, when the key is inserted, the key may come into contact with the light-storage chip, thereby damaging the light-storage chip.
[0006] In addition, in the above-mentioned conventional light-storage sheet, when used outdoors for a long time, the light-storage layer may be degraded by sunlight, and the light-storage performance may be deteriorated.
That is, when characters and the like are printed on the surface of the transparent synthetic resin layer as described above, the boundary between the printed layer and the light-storage layer may be discolored due to uneven heat, and the light-storage layer may deteriorate and become discolored (whitened).

Abstract

The invention provides a key cylinder capable of preventing a luminous sheet from being scratched when a key is inserted into a key insertion hole when the luminous sheet is disposed to surround the key insertion hole. In this key cylinder formed in such a manner that the key is inserted into the key insertion hole and rotated, the luminous sheet having a permeability enabling the storage of light in a luminous layer 36 and having a protective layer 34 with a hardness of a specified value or higher is disposed on the front surface side of the luminous layer 36 with a light emitting function so as to surround at least a part of the key insertion hole.

Description

technical field [0001] The present invention relates to a key cylinder that, for example, turns an ignition on or off, or locks or unlocks a locking device by inserting a key into a key insertion hole and turning it. Background technique [0002] For example, in a motorcycle, when a key is inserted into a key holder at night or the like, there is a problem that it is difficult to see the key insertion hole. In order to easily insert the key at night, etc., it is effective to surround the key insertion hole with a phosphor film. [0003] As a light storage sheet for such a key holder, for example, the surface of the light storage layer having a light storage pigment is covered with a transparent synthetic resin layer containing an ultraviolet absorber, and characters or symbols are printed on the surface of the transparent synthetic resin layer. substances (for example, refer to Patent Document 1). [0004] Patent Document 1 is Japanese Patent Application Laid-Open No. Sho ...
