FIG. 6 is a cross-sectional view showing a part of the procedure for attaching the gripping member 50 to the housing 11. FIG. 7 is a sectional view showing another part of the procedure for attaching the gripping member 50 to the housing 11. As shown in FIG. 6, the operator who attaches the gripping member 50 to the casing 11 approaches the main body 51 provided with the plurality of claws 60 from the inside of the casing 11 to the opening 11d, and then closes the main body 51. Insert the front end (+X side) into the opening 11d. As shown in FIG. 7, the operator pushes the main body 51 into the opening 11d until the plurality of claws 60 abut the protrusions 11e provided on the peripheral edge of the opening 11d from the rear side (-X side). insert. The portion of the main body portion 51 inserted into the opening 11d is fitted into the opening 11d. The main body portion 51 is held in the opening 11d and temporarily fixed to the opening 11d.

Note that in the case of the gripping member 50 attached to the front panel 11a, the work of inserting the main body portion 51 from the inside of the housing 11 is performed, for example, with the front panel 11a removed from the housing 11.

As shown in FIG. 7, the worker moves the outer member 52 close to the main body 51 temporarily fixed to the opening 11d from the outside of the casing 11, and fixes the outer member 52 to the main body 51. . For example, when fixing the outer member 52 with an adhesive, the outer member 52 is fixed in contact with the main body 51 with the adhesive applied to at least one of the main body 51 and the outer member 52. Further, for example, when fixing the outer member 52 to the main body part 51 by welding, the outer member 52 is held with a jig or the like in a state in which it is in contact with the peripheral edge of the opening 11d on the outer surface of the housing 11, The contact portion between the main body portion 51 and the outer member 52 is connected by welding. As described above, in the first embodiment, the gripping member 50 can be attached to the opening 11d of the housing 11. When the gripping member 50 is attached to the housing 11, the peripheral edge of the opening 11d is sandwiched between the plurality of claws 60 and the outer member 52. This prevents the gripping member 50 from coming off from the opening 11d.

Note that the method of attaching the gripping member 50 to the opening 11d is not limited to the method described above. For example, after tilting the main body 51 provided with the plurality of claws 60 obliquely with respect to the vertical direction Z and inserting the main body 51 into the opening 11d from the outside of the housing 11, The main body part 51 may be held in the opening 11d in a state as shown in FIG. 7 by returning the inclination with respect to the vertical direction Z.

When attaching a conventional gripping member by inserting it into the opening 11d from the outside of the housing 11, first insert the claw provided on one side in the vertical direction Z into the opening 11d, and then insert the gripping member in the vertical direction Z. Push all the claws provided on the other side into the opening 11d. At this time, at least one of the inner edge of the opening 11d and all the claws provided on the other side in the vertical direction Z is slightly elastically deformed, and the claw is pushed into the opening 11d. In this case, if the protruding height of the claw that is pushed in through elastic deformation is large, the claw gets caught on the inner edge of the opening 11d and cannot be pushed into the opening 11d. needed to be made smaller. Therefore, when attaching the conventional gripping member by pushing it into the opening 11d from the outside of the housing 11, it was difficult to make the claw portions have a sufficient protruding height, and it was difficult to firmly attach the gripping member to the housing 11.

On the other hand, according to the first embodiment, the outer member 52 that sandwiches the peripheral edge of the opening 11d between the plurality of claws 60 protruding from the main body 51 is separate from the main body 51, It is fixed to the main body part 51. Therefore, by first attaching the main body 51 to the opening 11d and then fixing the outer member 52 to the main body 51 attached to the opening 11d, the gripping member 50 can be held against the opening 11d with a large resistance. It can be easily installed without any problems. As a result, even if the protrusion height of the plurality of claw parts 60 protruding from the main body part 51 is large to some extent, the plurality of claw parts 60 can be removed by inserting the main part 51 into the opening 11d from the inside of the casing 11, for example. The main body 51 can be easily attached to the opening 11d with the claws 60 hooked onto the peripheral edge of the opening 11d. Therefore, the protruding heights of the claw portions 60 provided on both sides of the main body portion 51 in the vertical direction Z can be increased, and the gripping member 50 can be firmly attached to the opening portion 11d. As described above, according to the first embodiment, it is possible to improve the workability of attaching the gripping member 50 while ensuring the attachment strength of the gripping member 50.

Further, since the gripping member 50 can be attached to the housing 11 through the opening 11d of the housing 11 as described above, as long as the opening 11d is provided to the housing 11, the gripping member 50 can be attached to any part of the housing 11. The gripping member 50 can also be attached to. As a result, the degree of freedom in designing the attachment location of the gripping member 50 in the housing 11 can be improved compared to the case where the gripping member 50 is held between two or more members forming the housing 11. Therefore, the gripping member 50 can be attached to a location of the housing 11 that is easy for the operator to grip. Moreover, since the gripping member 50 can be attached to the opening 11d by finally fixing the outer member 52 to the main body 51 from the outside of the housing 11, the gripping member 50 can be attached to the opening 11d from the outside of the housing 11. You can easily check whether it is installed correctly.

Further, according to the first embodiment, the outer member 52 has a frame-shaped frame portion 52f along the opening edge 51e of the main body portion 51. The frame portion 52f is located outside the housing 11, and holds the peripheral edge of the opening 11d between the plurality of claw portions 60. Therefore, the frame portion 52f and the plurality of claw portions 60 can more stably sandwich the peripheral edge of the opening 11d, and the gripping member 50 can be more firmly attached to the opening 11d.
