Even if the thickness of the insertion portion 131 is less than the convex length of the convex portion 154b of the insertion port 153, the insertion portion 131 is released up to the convex portion 154b.

  Thereafter, holding the handle portion 132, the insertion portion 131 of the jig 130 is pulled out between the inner peripheral surface of the insertion port 153 of the flange portion 152 and the protruding piece 162 a of the decorative panel 160. At this time, the engagement protrusion 133 provided on the insertion portion 131 is brought into contact with the outer edge portion 163 of the decorative panel 160 to pull out the insertion portion 131. Since the engagement protrusion 133 of the insertion portion 131 is engaged with the outer edge portion 163 of the decorative panel 160, the protruding piece 162 b is also extracted as the insertion portion 131 is pulled out.

  Further, since the insertion portion 131 of the jig 130 has a thickness wider than the interval between the inner peripheral surface of the insertion port 153 and the protruding piece 162b, the insertion portion 131 of the jig 130 presses the protruding piece 162b, and the insertion portion 131 is inserted. Since the frictional force acts between the protruding piece 162b and the protruding piece 162b, the protruding piece 162b is also extracted by this frictional force.

  In this way, when the insertion portion 131 of the jig 130 is pulled out from between the inner peripheral surface of the insertion port 153 of the flange portion 152 and the protruding piece 162b of the decorative panel 160, the protruding piece 162b is moved along with the pulling out of the inserting portion 131. Extracted.

  And the convex part 164a of the protrusion piece 162a latched by the recessed part 154a of the insertion port 153 arrange | positioned above the flange part 152 is cancelled | released, and the decorative panel 160 is removed. The release of this locking can be naturally released by extracting the concave portion 164b of the protruding piece 162b locked to the convex portion 154b of the insertion port 153 disposed below the flange portion 152.

<Summary of Embodiment 2>
According to the electronic device 100 of the second embodiment, the concave piece 164b is provided in the protruding piece 162b disposed below the decorative panel 160, and the convex portion 154b is provided in the insertion port 153 disposed below the flange portion 152. 160 is inserted by inserting the protruding piece 162b into the insertion port 153 and locking the concave portion 164b of the protruding piece 162b and the convex portion 154b of the insertion port 153, and the decorative panel 160 is detached from the insertion port 153. The jig 130 is inserted between the piece 162b to release the locking between the concave portion 164b of the protruding piece 162b and the convex portion 154b of the insertion port 153, and the protruding piece 162b is extracted from the insertion port 153 while the jig 130 is pulled out. Therefore, it is easy to lock and release the protruding piece 162b with respect to the insertion port 153.

  Moreover, since the recessed part 164b is provided in the protrusion piece 162b, and the convex part 154b is provided in the insertion port 153, the structure of the latching and releasing of the protrusion piece 162b with respect to the insertion port 153 is easy.

  Further, since the guide surface 156 for inserting the jig 130 obliquely is provided at the insertion port 153, it is easy to insert the jig insertion portion between the protruding piece 162b and the insertion port 153.

  Further, the thickness of the insertion portion 131 of the jig 130 is set to be equal to or greater than the convex length of the convex portion 154b of the insertion port 153, and the concave portion 164b of the protruding piece 162b and the convex portion 154b of the insertion port 153 with the insertion of the insertion portion 131 of the jig 130 Therefore, the insertion of the insertion portion 131 of the jig 130 between the protruding piece 162b and the insertion port 153 enables the locking of the concave portion 164b of the protruding piece 162b with respect to the convex portion 154b of the insertion port 153. Can be canceled. Regarding the thickness of the insertion portion 131 of the jig 130, for example, even if the thickness of the insertion portion 131 is less than the convex length of the convex portion 154b of the insertion port 153, it is inevitable if the insertion portion 131 is inserted to the convex portion 154b. In addition, the locking of the concave portion 164b of the protruding piece 162b with respect to the convex portion 154b of the insertion port 153 can be released.

  In the second embodiment, the outer peripheral end surface 155 of the insertion port 153 disposed above the flange portion 152 is defined as the concave portion 154a. However, the concave portion 154a is provided on the inner peripheral surface of the insertion port 153 or is replaced with the concave portion 154a. In addition, another convex portion that engages with the convex portion 164a of the protruding piece 162a may be provided.

  Further, in the second embodiment, the engagement protrusion 133 is provided in the insertion portion 131 and the engagement protrusion 133 is brought into contact with the outer edge portion 163 of the decorative panel 160. However, as shown in FIG. The engaging protrusion 133 may not be provided. In this case, as shown in FIG. 13, the planar surface of the insertion portion 131 of the jig 130 only comes into contact with the outer edge portion 163 of the decorative panel 160, but the friction between the outer edge portion 163 and the surface of the insertion portion 131. Since the protruding piece 162b can be easily extracted by the force, the decorative panel 160 can be easily removed. In order to further increase the frictional force, a material having a large friction coefficient may be used, or the surface may be roughened.

  In the second embodiment, the insertion portion 131 of the jig 130 has a thickness wider than the interval between the inner peripheral surface of the insertion port 153 and the protruding piece 162b, but may be narrower than the interval. In that case, the insertion portion 131 of the jig 130 does not press the protruding piece 162b, and the frictional force is unlikely to act between the inserting portion 131 and the protruding piece 162b, so the insertion portion 131 is attached to the outer edge portion 163 of the decorative panel 160. As described above, the protruding piece 162b may be extracted by the frictional force between the outer edge portion 163 and the surface of the insertion portion 131 as described above.
