On the substrate 96, an electronic component 961, a connector connecting portion 962, and other electronic components are mounted that protrude to a position higher than the height of the substrate case 91. As shown in FIG.

The wall portion main body 93 is formed in a wall shape rising from the peripheral portion of the bottom portion 92 toward the front side Y1. The wall portion main body 93 is provided in a wall shape along the peripheral portion of the bottom portion 92 in the entire circumferential direction.

The stepped portion 94 is provided at an end portion on the front side Y1 of the wall portion main body 93 (an end portion of the wall portion main body 93 opposite to the bottom portion 92). The stepped portion 94 is provided over the entire circumferential area of the wall portion main body 93 . The stepped portion 94 has a middle stepped portion 941 (laterally extending portion), a stepped portion side wall portion 942 , and a plurality of reinforcing plates 943 .

The middle step portion 941 extends from the front Y1 end of the wall body 93 (the end of the wall body 93 opposite to the bottom 92 ) to the outside of the wall body 93 and extends substantially parallel to the bottom 92 . with a predetermined width. The intermediate step portion 941 is formed over the entire circumferential area of the end portion of the wall portion main body 93 of the substrate case 91 .

The step portion side wall portion 942 is formed in a wall shape rising from the outer end portion of the intermediate step portion 941 toward the front side Y1. The stepped portion side wall portion 942 is provided like a wall along the outer peripheral edge portion of the intermediate stepped portion 941 in the entire circumferential direction.

A plurality of reinforcing plates 943 reinforce the stepped portion 94 . A plurality of reinforcing plates 943 are formed in plate shapes that connect the intermediate step portion 941 and the step portion side wall portion 942 . A plurality of reinforcing plates 943 are provided at intervals in the circumferential direction.

In this embodiment, as shown in FIG. 4, the stepped portion 94 includes an upper end stepped portion 94a provided at the upper end of the board case 91, a lower end stepped portion 94b provided at the lower end of the board case 91, and It has a one-side stepped portion 94c provided on the one side X1 and the other-side stepped portion 94d provided on the other side X2 in the left-right direction X. The width of the middle stepped portion 941 of the one side stepped portion 94c and the other side stepped portion 94d is formed to be larger than the width of the middle stepped portion 941 of the upper end stepped portion 94a and the lower end stepped portion 94b.

In the substrate case 91, a connector connecting portion 962 is arranged inside the one-side stepped portion 94c at a position adjacent to the one-side stepped portion 94c. The one-side step portion 94 c has a middle step portion 941 and a step portion side wall portion 942 . The middle step portion 941 extends from the front Y1 end of the wall body 93 (the end of the wall body 93 opposite to the bottom 92 ) to the outside of the wall body 93 and extends substantially parallel to the bottom 92 . with a predetermined width. The step portion side wall portion 942 rises from the outer end portion of the intermediate step portion 941 .

As a result, since the one-side stepped portion 94c is provided with the middle stepped portion 941 and the stepped portion side wall portion 942, when attaching or detaching the connector 11, the worker can place his or her finger in the space S on the front side Y1 of the middle stepped portion 941. can be placed. Therefore, since fingers do not touch the side wall portion 942 of the stepped portion, the attaching/detaching work of the connector 11 is facilitated.

The guard part 95 is provided at the lower end of the board case 91, as shown in FIGS. The guard part 95 is formed so as to protrude outward from the lower side of the board case 91 . The guard portion 95 guards the harness (wiring) and the like from contacting the head portion 811 (metal part) of the screw 81, which is a component of the lifting device 8, for example. The guard part 95 is provided, for example, above the head 811 of the screw 81 arranged on the upper part of the lifting device 8 .

The guard portion 95 has a side protruding plate 951 protruding laterally on the front side Y1 and a downward protruding plate 952 protruding downward from the tip of the side protruding plate 951 . By guarding the upper side and the front side of the head 811 (metal part) of the screw 81, which is a component of the lifting device 8, by the guard part 95, the harness (wiring) or the like is blocked by the head 811 (metal part) of the screw 81. ) are guarded against contact.

The potting material 97 is filled from the bottom 92 of the substrate case 91 to the height of the wall main body 93 as shown in FIG. The potting material 97 fixes the substrate 96 to the substrate case 91 by being filled with a resin material in a solution state and hardened. The potting material 97 is filled in a range from the bottom 92 of the board case 91 to the height of the wall main body 93 to fix the board 96 , the electronic component 961 and the connector connecting part 962 . The potting material 97 is not filled in the stepped portion 94 .

In the board forming part 9 described above, the stepped part 94 is provided at the end of the front side Y1 of the wall main body 93 of the board case 91, so that the connector 11 is connected to the connector connection part 962 by the intermediate stepped part 941 of the stepped part 94. A space S for arranging the operator's fingers when attaching and detaching can be secured. Therefore, the connector 11 can be easily attached/detached to/from the connector connection portion 962 .

Here, in order to facilitate attachment and detachment of the connector 11 to and from the connector connection portion 962, it is assumed that the wall portion main body 93 is moved outward without providing the stepped portion 94, and the connector is connected. It is conceivable to provide a space on the side of the portion 962 . In this case, when the wall body 93 is formed by moving it outward, the area of the bottom part 92 of the board case 91 is increased by the amount of movement of the wall body 93 outward. This increases the amount of potting material 97 used. In contrast, in the present disclosure, by providing the stepped portion 94 without moving the wall portion main body 93 outward, the stepped portion 94 does not need to be filled with the potting material 97 . As a result, the connector 11 can be easily attached to and detached from the connector connecting portion 962 while suppressing the amount of the potting material 97 used.
