  The locking projection 43 includes a contact surface 43b that is perpendicular to the direction A in which the instrument unit 1 and the panel 2 are brought into contact with and separated from each other and contacts the edge of the hole 24a when locked in the hole 24a. Accordingly, when the instrument unit 1 and the panel 2 are relatively separated from each other, the contact surface 43b contacts the edge of the hole 24a. Accordingly, the instrument unit 1 can be securely attached to the panel 2 without inadvertently releasing the locking projection 43 into the hole 24a.

  The elastic arm 42 is elastically deformed by the locking release portion 6 being pressed in the direction S opposite to the direction in which the locking projection 43 protrudes. The instrument unit 1 can be detached from the panel 2 by releasing the lock.

  Since the seat portion 7 that protrudes in the vicinity of the unlocking portion 6 is provided, when removing the instrument unit 1 from the panel 2, the operator presses one finger of one hand against the seat portion 7 and the other finger. Then, the lock release unit 6 is operated, and the instrument unit 1 can be pulled in this state. Therefore, the workability at the time of removal can be improved, and the instrument unit 1 can be easily detached from the panel 2.

  Since the first claw portion 4 is press-fitted into the hole 24a and the locking projection 43 is locked into the hole 24a, the first claw portion 4 does not rattle within the hole 24a, and vibration during travel of the moving body It is possible to prevent the generation of abnormal noise due to the like. Further, when the instrument unit 1 receives a force in a direction away from the panel 2, the frictional force described above is generated between the first claw portion 4 and the hole 24a, and the instrument unit 1 starts to move. The power can be effectively deterred.

  In the present embodiment, the instrument unit 1 includes a display instrument 11 (that is, a tachometer 11a, a speedometer 11b, a temperature gauge 11c, and a fuel gauge 11d) and a case 3, and the case 3 is provided with claws 4 and 5. It was. However, for example, the first claw portion 5 may be directly provided on the tachometer 11a as an instrument unit.

  Further, in the present embodiment, two first claw portions 4 and two second claw portions 5 are provided. However, if at least one first claw portion 4 is provided, these claw portions are provided. The numbers of 4 and 5 are not limited at all.

  Moreover, in this embodiment, the 1st nail | claw part 4 and the 2nd nail | claw part 5 are provided in the four corners of the case 3, the 1st claw part 4 is on the upper side of the case 3, and the 2nd claw part 5 is provided. However, the positions of the claws 4 and 5 are not limited at all. In addition, when the 1st nail | claw part 4 is provided near the gravity center of the instrument unit 1, the instrument unit 1 attached to the panel 2 is stable and preferable.

  In addition, embodiment mentioned above only showed the typical form of this invention, and this invention is not limited to embodiment. That is, various modifications can be made without departing from the scope of the present invention.

It is a perspective view which shows the instrument unit and panel concerning one Embodiment of this invention. It is a perspective view from another direction of the meter unit shown by FIG. FIG. 3 is a top view (partial cross-sectional view) showing a first claw portion and a vicinity of a hole shown in FIG. 2. It is an upper surface (partial cross section) figure which shows the time when the elastic arm shown by FIG. FIG. 5 is a top view (partially cross-sectional view) showing the elastic arm shown in FIG. 4 in a locked state. It is a bottom view of the 2nd nail | claw part shown by FIG. It is a side view of the 2nd nail | claw part shown by FIG. It is a perspective view which expands and shows the latch release part and seat part which were shown by FIG.
