## Abstract

A wiring module that can account for tolerance in an alignment direction of a plurality of power storage devices includes: a first unit row including a plurality of first units linked by a first warping linking portion and a first slide linking portion that enable adjustment of an interval between the plurality of first units, the first warping linking portion having a warping portion and the linking portion having an inner wall and an outer wall; a second unit row including a plurality of second units linked by a second linking portion having an inner wall and an outer wall and enables adjustment of an interval between the plurality of second units, the second unit row being disposed side-by-side with the first unit row; and a row linking portion that has a variable row-interval portion that enables adjustment of an interval between the first and the second unit rows.

## Claims

### Claim 1

A wiring module configured to be provided on a power storage device group in which a plurality of power storage devices that each have an electrode terminal are arranged side-by-side in an alignment direction, the wiring module comprising:
a first unit row including a plurality of first units that each house at least one first bus bar configured to be connected to a corresponding electrode terminal, the plurality of first units being linked by a first linking portion having a first variable interval portion that enables adjustment of an interval between the plurality of first units;
a second unit row including a plurality of second units that each house at least one second bus bar configured to be connected to a corresponding electrode terminal, the plurality of second units being linked by a second linking portion having a second variable interval portion that enables adjustment of an interval between the plurality of second units, and the second unit row being disposed side-by-side with the first unit row; and
a row linking portion that is connected to both the first unit row and the second unit row and links the first unit row and the second unit row, and includes a variable row-interval portion that enables adjustment of an interval between the first unit row and the second unit row.

### Claim 2 (depends on 1)

The wiring module according to claim 1,
wherein a first routing portion provided in the first unit row includes a first extension portion that extends toward the second unit row,
a second routing portion provided in the second unit row includes a second extension portion that extends toward the first unit row and is arranged partially overlapped with the first extension portion, and
a wire is disposed in the first routing portion, the first extension portion, the second routing portion, and the second extension portion.
