1. A storage battery module comprising:
- a storage battery group in which storage batteries are stacked in a stacking direction;
end plates located at both ends in the stacking direction of the storage battery group;
a coupling band coupled to the end plates, thereby coupling the end plates to each other, the coupling band having an inside surface that faces upper surfaces of the storage batteries; and
a pressing device that presses the storage battery group, whereinthe pressing device includes pin-shaped members that extend and protrude from the inside surface of the coupling band in a direction orthogonal to the stacking direction and that press the storage batteries in an identical direction, the inside surface of the coupling band being spaced apart from the upper surfaces of the storage batteries, the pressing device including a fixing portion that fixes the pin-shaped members to the coupling band.

Abstract
A storage battery module includes a storage battery group, first and second end plates, a coupling band, and a pressing device. The storage battery group includes storage batteries stacked in a stacking direction and has a first end and a second end opposite to the first end in the stacking direction. The first and second end plates are provided at the first and second ends, respectively. The coupling band couples the first and second end plates to each other. The pressing device includes pin-shaped members pressing the storage batteries in a pressing direction and a fixing portion fixing the pin-shaped members to the coupling band.
