- the base end surface 23 is disposed on the grip portion end surface 22c side surface of the grip portion main body 220, and is formed substantially at the center in the width direction X of the grip portion end surface 22c.
- the cover member 4 is a member made of resin that covers the gripping portion main body 220 and constitutes the gripping portion 22 together with the gripping portion main body 220 .
- the cover member 4 constitutes the grip portion surface 22a, the grip portion back surface 22b, and the grip portion end surface 22c except for the base end surface 23.
- the cover member 4 has an opening 41 , an edge portion 42 and a step 43 .
- the opening 41 is a polygonal through hole formed in a portion corresponding to the base end surface 23 of the grip portion body 220 .
- the edge portion 42 is the peripheral edge of the opening 41 and is arranged around the base end surface 23 .
- a step 43 is formed between the edge portion 42 and the base end surface 23 .
- the resin-made cover member 4 covers the metallic grasping portion main body 220 , the proximal end surface 23 in the opening 41 through which the proximal end surface 23 is exposed is more likely than the circumference of the proximal end surface 23 of the grasping portion 22 . placed in a recessed position. Therefore, a step 43 corresponding to the thickness of the cover member 4 is formed between the base end face 23 and the surrounding portion of the base end face 23 .
- the key information 3 is a two-dimensional code 30 and has information in both vertical and horizontal directions.
- the two-dimensional code 30 may be, for example, a QR code (registered trademark).
- the key information 3 is represented two-dimensionally and displayed on the plane of the key body 2 . Specifically, the key information 3 is engraved on the base end face 23 by laser marking.
- the key information 3 is configured to be readable by an electronic device such as a smart phone as a reader.
- the reader is equipped with automatic recognition technology and has a dedicated reading application installed.
