Have The lid portion is formed with a notch hole that is exposed to the upper side of the one side wall while accommodating any one of the plurality of wire pressing pieces when the wire storing groove portion is closed. To do.

  With this configuration, in the battery wiring module of the present invention, even if a part of the detection wire is at a position where it can protrude from the proximal end side of the wire holding piece or the hinge side of the lid portion, it can be easily removed from the outside through the notch hole. It can also be visually recognized and can be pushed into the wire housing groove side through the notch hole. Therefore, it becomes a battery wiring module which can prevent reliably that the detection electric wire remains stuck.

  In the battery wiring module of the present invention, the cutout hole has an inner peripheral edge portion that separates a gap in at least the length direction of the wire housing groove portion with respect to any of the plurality of wire pressing pieces. Is good.

  In this case, by appropriately setting the gap in the groove length direction of the electric wire storage groove, the storage state of the detection electric wire can be easily observed, and a part of the detection electric wire protrudes on the electric wire presser piece when the lid is closed. Even if this occurs, it is possible to reliably prevent damage to the detection wires.

  In the battery wiring module of the present invention, the base end portions of the plurality of wire pressing pieces are located on the upper side away from the inner bottom wall surface of the wire housing groove portion from the hinge coupling position of the lid portion, and It is preferable to incline so that the protruding end portion of the presser piece is located below the base end portion.

  In this case, since the wire holding piece is inclined obliquely downward at least on the protruding end side, it becomes easy to guide the detection wire into the inside of the wire storage groove, and the detection wire entering the wire storage groove is outward. It becomes difficult to jump out. Moreover, even if the detection electric wire has come out on the electric wire pressing piece when the lid portion is closed, the detection electric wire is easily pushed into the electric wire housing groove portion as the lid portion rotates in the closing direction.

  In the battery wiring module of the present invention, the inner peripheral edge portion of the notch hole and the plurality of wire holding pieces are the same on the lower surface side of the plurality of wire holding pieces near the inner bottom wall surface of the wire housing groove. A height electric wire path regulating surface may be formed.

  With this configuration, when the lid is closed, the multiple detection wires in the wire storage groove are not partially pressed by the wire holding piece, and it is difficult to damage the detection wires. It becomes a module.

  According to the present invention, even if a part of the detection electric wire is in a position where it can protrude from the proximal end side of the electric wire holding piece or the hinge side of the lid portion, it can be visually recognized from the outside or pushed into the electric wire storage groove portion side. Therefore, it is possible to provide a highly reliable battery wiring module that can reliably prevent the detection electric wire from being stuck.
