且つ安価に提供することができる。Further, the keyhole peripheral member is provided separately from the key, and the keyhole peripheral member at the peripheral portion of the keyhole portion is abuttable to contact the keyhole peripheral member while the insertion portion is inserted into the keyhole portion. An urging means that is movably attached to the insertion portion via the operation portion along the axis, and urges the contact protrusion to move toward the insertion portion along the key axis, and the contact protrusion. Each of the keys is provided with a rotation lock mechanism that locks relative rotation around the key axis of the insertion section and the operation section in a state where the operation section is close to the insertion section side. Since the cam portion that rides on the contact convex portion and releases the rotation lock mechanism is formed on the key hole peripheral member, the contact convex portion is attached when the key is not inserted into the key hole portion. It is always urged by the urging means to be close to the insertion portion side, and as a result, By the action of the rolling lock mechanism, the relative rotation of the insertion portion and the operation portion around the key axis is locked, and it becomes possible to maintain a state in which the display of the locking (or unlocking) operation by the display unit does not change. Even if the key is carried around after being locked (or unlocked), it is possible to prevent the display from being changed carelessly. Further, in the state where the key is inserted into the keyhole, unless the abutting convex portion rides on the cam portion of the keyhole peripheral member, the rotation lock mechanism works to integrally rotate the operation portion and the insertion portion. The lock can be locked (or unlocked) while the key is rotated so that the abutment protrusion rides on the cam, and the rotation lock mechanism is released to allow the insertion part and the operating part to move relative to each other. It becomes possible to rotate, and it becomes possible to change the display of the display unit. Therefore, by simply inserting the key into the keyhole and rotating it around the key axis, it is possible to automatically change the display of the display and lock (or unlock) it from a series of operations. Becomes In addition, each of the above-described configurations can be formed without using a complicated and special structure, and thus can be provided with a simple structure at low cost.

A first fitting concave portion 12 into which the rotary shaft portion 8 is fitted and a second fitting concave portion 13 into which the contact convex portion 10 is fitted are formed separately. Further, on one of the split operation main bodies 9a, there is provided a rotation limiting convex portion 14 which allows the insertion portion 5 and the operation portion 6 which rotate relative to each other about the key axis to rotate only half a rotation. The rotation shaft portion 8 is integrally connected to the end edge and
A window portion 15 is formed in the bottom portion of the first fitting recess 12 so as to expose approximately half the circumference of the colored portion 8a formed in the above.
The two split operation main bodies 9a and 9b are integrated with each other while sandwiching the contact projection 10, the coil spring 11, and the rotary shaft portion 8 therebetween. The rotation limiting convex portion 14 is
As the operation part 6 is rotated around the rotation shaft part 8,
By contacting the concave portion 7b of the insertion body 7 located at a part of the rotation locus, there is a function of allowing only half rotation relative rotation. Further, the window portion 15 displays the red color of the colored portion 8a in a state where the operation portion 6 is rotated to the right with respect to the rotary shaft portion 8 (locked state) and is rotated to the left (locked state). In the released state), the color of the colored portion 8a is configured to be displayed in blue, and the last key operation is a locking operation (displayed in red) only by looking at the display color of the window portion 15. Whether it was the lock release operation (displayed in blue) was obvious. That is, the relative postures of the insertion portion 5 and the operation portion 6 around the key axis are as follows:

A rectangular flange 10b is formed to prevent rotation around the axis of the contact protrusion. The base end of the contact protrusion 10 including the square flange 10b is fitted in the second fitting recess 13, and is inserted into the operation body 9 along the key axis direction. It is attached so that it can move in and out on the 5 side. On the other hand, an intermediate portion in the longitudinal direction of the contact convex portion 10 is fitted to the base end portion of the insertion main body 7 as it protrudes toward the insertion portion 5 side,
A first fitting portion 16 (an example of a rotation lock mechanism R) that can prevent relative rotation between the insertion portion 5 and the operation portion 6 is integrally provided. As shown in the drawing, the first fitting portion 16 is formed in a U-shaped cross section, and a concave portion of the "U" has a
By inserting the side edge portion of the insertion body 7, relative rotation between the insertion portion 5 and the operation portion 6 can be prevented. Further, the coil spring 11 is housed in the second fitting recess 13 so that the contact projection 10 is projected toward the insertion side.
