## Abstract

An energy storage apparatus includes an energy storage device including a surface having a first end face from which an external terminal protrudes and a second end face on an opposite side from the first end face and a retaining member that includes paired end members disposed on opposite sides of the energy storage device in a second direction orthogonal to a first direction in which the external terminal protrudes and a coupling portion for coupling the paired end members. The coupling portion includes a main body portion facing the energy storage device in a third direction orthogonal to the first direction and the second direction, a first extending portion extending along the first end face from the main body portion, and an end extending portion extending along the end member from the main body portion, a drain portion is provided to a position of the energy storage apparatus near the second end face, and the main body portion, the first extending portion, and the end extending portion are connected to each other to thereby form a first end corner portion of the coupling portion.

## Claims

### Claim 1

An energy storage apparatus comprising:
an energy storage device including a surface having a first end face from which an external terminal protrudes and a second end face on an opposite side from the first end face; and
a retaining member that includes paired end portions disposed on opposite sides of the energy storage device in a second direction orthogonal to a first direction in which the external terminal protrudes and a coupling portion for coupling the paired end portions and that retains the energy storage device,
wherein the coupling portion includes
a main body portion facing the energy storage device in a third direction orthogonal to the first direction and the second direction,
a first extending portion extending along the first end face from the main body portion, and
an end extending portion extending along the end portion from the main body portion,
a drain portion is provided to a position of the energy storage apparatus near the second end face, and
the main body portion, the first extending portion, and the end extending portion are continuously connected to each other to thereby form first end corner portions of the coupling portion;
the energy storage apparatus further comprising an insulating member for covering at least a face of the coupling portion facing the energy storage device,
wherein the coupling portion has a second extending portion extending along the second end face from the main body portion,
the insulating member has a convex part positioned astride the main body portion and the second extending portion between each of the end portions and the energy storage device adjacent to the end portion, and
the drain portion is disposed on an outer side of the convex portion in the second direction.

### Claim 2 (depends on 1)

The energy storage apparatus according to claim 1,
wherein the first extending portion and the second extending portion respectively and continuously extend from one of the end portions to the other end portion in the second direction, and
a dimension of the second extending portion is larger than a dimension of the first extending portion in the third direction.

### Claim 3 (depends on 1)

A moving body comprising:
the energy storage apparatus according to claim 1;
a moving body main body mounted with the energy storage apparatus; and
a drive portion for driving the moving body main body by using electric power supplied from the energy storage apparatus,
wherein the energy storage apparatus is disposed with the drain portion positioned at a lower end portion of the energy storage apparatus.

### Claim 4 (depends on 1)

An energy storage system comprising:
the energy storage apparatus according to claim 1;
an energy storage system main body mounted with the energy storage apparatus; and
an input/output terminal which is connected to the energy storage apparatus and through which electric power can be input from outside and output to the outside,
wherein the energy storage apparatus is disposed with the drain portion positioned at a lower end portion of the energy storage apparatus.
