  • each second locking protrusion 322aA protrudes toward the inside of the first left guide groove 320A in the Y direction. That is, when viewed from the X direction, the left second locking protrusion 322aA protrudes toward the right, and the right second locking protrusion 322aA protrudes toward the left.
  • the upper surface of each second locking protrusion 322aA is inclined downward as it approaches the inside of the first left guide groove 320A in the Y direction.
  • the lower surface of each second locking protrusion 322aA is inclined upward as it approaches the inside of the first left guide groove 320A in the Y direction.
  • the pair of first locking portions 312A form a locking structure that locks the first low-voltage wiring member 510A inserted into the first right guide groove 310A. Specifically, the pair of first locking portions 312A detachably lock the first low-voltage wiring member 510A into the first right guide groove 310A.

  • the pair of first locking portions 312A no longer receive external force from the first low-voltage wiring member 510A, and the Y-direction deflection of the pair of first locking portions 312A is released. Therefore, the minimum value of the Y-direction width of the gap between the pair of first locking protrusions 312aA becomes less than the diameter of the first low-voltage wiring member 510A in a direction perpendicular to the X-direction. Therefore, it is possible to prevent the first low-voltage wiring member 510A from detaching from the first right guide groove 310A through the gap between the pair of first locking protrusions 312aA. Therefore, the first low-voltage wiring member 510A is locked in the first right guide groove 310A.

  • each first locking projection 312aA when viewed from the X direction, the upper surface of each first locking projection 312aA is inclined downward as it approaches the inside of the first right guide groove 310A in the Y direction. Therefore, compared to when the upper surface of each first locking projection 312aA is approximately parallel to the Y direction, when the first low-voltage wiring member 510A is pushed toward the first right guide groove 310A with the lower surface of the first low-voltage wiring member 510A and the upper surfaces of each first locking projection 312aA in contact with each other, the pair of first locking portions 312A can be easily deflected toward the outside of the first right guide groove 310A in the Y direction.
  • each first locking projection 312aA when viewed from the X direction, the lower surface of each first locking projection 312aA is inclined upward as it approaches the inside of the first right guide groove 310A in the Y direction. Therefore, compared to a case in which the upper surface of each first locking projection 312aA is approximately parallel to the Y direction, when the first low-voltage wiring member 510A is pushed upward into the first right guide groove 310A with the upper surface of the first low-voltage wiring member 510A and the lower surfaces of each first locking projection 312aA in contact with each other, the pair of first locking portions 312A can be easily deflected toward the outside of the first right guide groove 310A in the Y direction.
  • each first locking protrusion 312aA when viewed from the X direction, is curved along the outer surface of the first low-voltage wiring member 510A inserted into the first right guide groove 310A. Therefore, when viewed from the X direction, the gap between the lower surface of each first locking protrusion 312aA and the outer surface of the first low-voltage wiring member 510A can be reduced. Therefore, rattling of the first low-voltage wiring member 510A within the first right guide groove 310A can be suppressed.

Specifically, none of the first locking portions 312A provided on the first partition 308A and none of the second locking portions 322A provided on the first partition 308A are aligned in the X-direction.
  • the strength of the first partition 308A around each of the first locking portions 312A and each of the second locking portions 322A can be improved with the width of the first partition 308A in the Y-direction narrowed. Therefore, in this embodiment, it is possible to achieve both a smaller size and higher strength for the first guide member 300A compared to the above-mentioned case.
  • the X-direction spacing between each first locking portion 312A provided on first partition 308A and each second locking portion 322A provided on first partition 308A can be, for example, 50% or more of the Y-direction width of first partition 308A.

Therefore, the Z-direction position of the first support 400A is higher than the Z-direction position of the first low voltage wiring member 510A and the Z-direction position of the first lower high voltage wiring member 520A. Therefore, the upper high voltage wiring member 530 can be supported at a higher position in the Z direction than the first right guide groove 310A and the first left guide groove 320A.
  • noise interference between the upper high voltage wiring member 530 and the first low voltage wiring member 510A can be suppressed compared to the case where the Z-direction position of the upper high voltage wiring member 530 and the Z-direction position of the first low voltage wiring member 510A are aligned in the Z direction.

  • the relationship between the diameter of the first low-voltage wiring member 510A, the diameter of the first lower high-voltage wiring member 520A, and the diameter of the upper high-voltage wiring member 530 is not limited to this example.
  • the positional relationship between the first low voltage wiring member 510A, the first lower high voltage wiring member 520A, and the upper high voltage wiring member 530 described with reference to Figures 9 and 3 can also be applied to the positional relationship between the second low voltage wiring member 510B, the second lower high voltage wiring member 520B, and the upper high voltage wiring member 530.
  • FIG. 10 shows a modified example of FIG. 7.
  • a convex portion 321A is provided on the upper surface of the first bottom portion 302A in the first left guide groove 320A.
  • the convex portion 321A is formed, for example, by a mark such as "LV" shown in FIG. 8.

Therefore, compared to when the protrusion 321A does not exist, it is possible to prevent the wiring member from being erroneously inserted into the first left guide groove 320A. Also, the markings such as "LV" can be visually recognized as grooves through which wiring for the Lower Voltage side should be passed.
