FIG. 12 is a perspective view of base 260 according to the present embodiment.
FIG. 13 is a sectional view of instrument body 200 in the present embodiment.
In the present embodiment, the base 260 holds the electric wire 50 wired inside the recess 210 in the cable holding space 901 that is a space surrounded by the bottom surface portion 211, the pair of side portions 262, and the plate portion 263. ..

As shown in FIGS. 12 and 13, the base 260 includes a pair of base legs 261 fixed to the bottom surface 211 of the instrument body 200 with screws or the like. In addition, the base portion 260 connects the side portions 262 formed to the opening 213 side from the outer end portions of the pair of base portion leg portions 261 and the end portions of the paired side portions 262, respectively. It has a bottom surface portion 211 and a plate portion 263 formed substantially in parallel. The distance between the pair of side portions 262 is formed to be equal to the distance of the pair of side surface portions 212 in the recess 210.

Further, the plate portion 263 includes a slit portion 263a into which the spring fixing portion 232 of the spring portion 230 is inserted, and a spring fixing hole 263b for fixing the spring fixing portion 232 with a screw or the like after the spring fixing portion 232 is inserted into the slit portion 263a. Are formed.
A cable guide portion 263c is formed on a pair of side edges 262b of the plate portion 263, which is different from the pair of side edges 262a on which the side portions 262 are formed. The cable guide portion 263c prevents the electric wire 50 from interfering with and damaging the end surfaces of the pair of side edges 262b of the plate portion 263 when the electric wire 50 is inserted, and also serves as a guide mechanism for the electric wire 50. The cable guide portion 263c forms a curved surface portion in which the end portion of the plate portion 263 is curved toward the attached portion 500 on each of the pair of side edges 262b of the plate portion 263, and the attached portion 500 or the bottom surface portion is formed. It is formed to be inclined to the side of 211.

The platform 260 forms a cable holding space 901 surrounded by the bottom surface portion 211, the pair of side portions 262, and the plate portion 263 when being placed in the recess 210.
The plate portion 263 is formed to have substantially the same length as the bottom surface portion 211 in the lateral direction, and the cable holding space 901 is large in the lateral direction and can be formed wide. Further, since the electric wire 50 has a shape to be inserted instead of being hooked, the electric wire 50 can be held more firmly than the hooked shape.
Further, the plate portion 263 is partially provided at least at three positions in the longitudinal direction of the recess 210 of the instrument body 200, as in the first embodiment. Therefore, the length of inserting the electric wire 50 is short, and the inserting work can be facilitated.

It should be noted that both the base 240 shown in the first embodiment and the base 260 shown in the second embodiment may be provided in one instrument body 200. For example, the base 260 may be disposed on the end side in the longitudinal direction and the base 240 may be disposed substantially at the center.

It should be noted that although the slit portion and the spring fixing hole are formed in each of the base portion 240 shown in the first embodiment and the base portion 260 shown in the second embodiment, the base portion arranged in the instrument main body 200. Among the base parts 240 and 260 in which the spring part 230 is not arranged, those without the slit part and the spring fixing hole may be used.

Although the first and second embodiments of the present invention have been described above, two or more of these embodiments may be combined and implemented. Alternatively, one of these embodiments may be partially implemented. Alternatively, two or more of these embodiments may be partially combined for implementation. In addition, these embodiments may be implemented in whole or in part in any combination.
Note that the above-described embodiments are essentially preferable examples, and are not intended to limit the scope of the present invention, its applications, and uses, and various modifications can be made as necessary. ..
