In this state, when the lock / unlock display key 10 continues to rotate clockwise, the case 12 further moves relative to the key body 14 (when the case 12 is in a state of being rotatable with respect to the key body 14). Rotating clockwise, the ball 16B of the holding portion 16 moves over the tapered portion of the contact surface 14F with the key body 14 and moves to the opposite side.

  By the movement of the case 12, the key body 14 is relatively moved to the “second position”, and the second surface 14B colored in red is visible from the second window 12D of the case 12. Thus, the first surface 14A of the key body 14 becomes invisible from the first window 12C of the case 12.

  On the other hand, considering the case where the lock is unlocked using the lock / unlock display key 10, after the key body 14 is inserted into the lock, the lock / unlock display key 10 is rotated counterclockwise (Y direction in FIG. 8). When the unlocking operation is performed, the rotation of the key body 14 is restricted after the unlocking is completed. In this state, if the lock / unlock display key 10 is further rotated counterclockwise, the case 12 is moved relative to the key body 14 (when the case 12 is in a state of being rotatable with respect to the key body 14). Further, it rotates counterclockwise, and the ball 16B of the holding portion 16 moves over the tapered portion of the contact surface 14F with the key body 14 and moves to the opposite side.

  Due to the movement of the case 12, the key body 14 relatively moves to the first position, and the first surface 14A colored in black becomes visible from the first window 12C of the case 12. The second surface 14B of the key body 14 becomes invisible from the second window 12D of the case 12.

  Therefore, when the user of the lock / unlock display key 10 can visually recognize the second surface 14B colored red from the second window 12D, the lock is in the locked state, and the first window 12C is blackened. When the colored first surface 14A is visible, it can be easily known that the lock is in the unlocked state.

  As described above, the lock / unlock display key 10 according to the present embodiment includes the case 12, the key body 14 that is partly housed in the case 12 and is rotatable with respect to the case 12, and the key body. 14, and the case 12 has at least one surface in the width direction of the key body 14 (in this embodiment, the first surface 14 </ b> A and the first surface 14 </ b> A). Windows (in this embodiment, a first window 12C and a second window 12D) are formed, and the key body 14 has at least one surface on the case 12 side. The first position that can be viewed from the windows 12C and 12D of the first and the second position that at least one surface cannot be viewed from the windows 12C and 12D of the case 12 can be rotated, and the holding portion 16 moves the key body 14 to the first position or the first position. Because it is configured to be able to be held at the position, it is possible to confirm the locking and unlocking even when the key is picked during the locking and unlocking operation as well as the confirmation of locking and unlocking when going out, etc. Convenience is high.

  In addition, since the first surface 14A or the second surface 14B of the key body 14 can be visually recognized from the windows 12C and 12D of the case 12, the locked state and the unlocked state can be clearly distinguished. The state of locking and unlocking can be easily and reliably identified

  In particular, the case 12 includes a first window 12C that allows the first surface 14A on one side in the width direction of the key body 14 to be visible from the outside of the case 12, and a second window on the other side in the width direction of the key body 14. A second window 12D is formed to make the surface 14B visible from the outside of the case 12, the key body 14 makes the first surface 14A visible from the first window 12C of the case 12, and the second The first position where the surface 14B of the case 12 is invisible from the second window 12D of the case 12, the second surface 14B is visible from the second window 12D of the case 12, and the first surface 14A is Since the first window 12C of the case 12 can be rotated between the first window 12C and the second position invisible, the two windows 12C and 12D disposed on both sides of the key body 14 in the width direction are used. You can confirm unlocking and unlocking, even more convenience It is possible to increase.

  In addition, since the first surface 14A and the second surface 14B are colored with different colors (red and black in the present embodiment), confirmation of locking / unlocking can be performed more quickly and reliably.

  The locking / unlocking display key according to the present invention is not limited to the above-described embodiment, and various changes can be made without departing from the scope of the present invention.
