## Abstract

A cylindrical battery housing case has a plurality of cylindrical battery housing chambers each housing one cylindrical battery, and a plurality of elongated resilient members each having a protrusion for holding a cylindrical portion of the cylindrical battery is formed in a cantilevered manner inside notches in a side wall of each of the cylindrical battery housing chambers.

## Claims

### Claim 1

A cylindrical battery housing case comprising:
a plurality of cylindrical battery housing chambers, each of the cylindrical battery housing chambers being configured to house one cylindrical battery, wherein
each of the cylindrical battery housing chambers comprises a side wall having a plurality of notches and a plurality of elongated resilient members provided in a cantilevered manner inside the notches, each of the elongated resilient members comprising a protrusion configured to hold a cylindrical portion of the cylindrical battery,
the plurality of cylindrical battery housing chambers comprises a first cylindrical battery housing chamber and a second cylindrical battery housing chamber adjacent to the first cylindrical battery housing chamber,
the plurality of elongated resilient members of the first cylindrical battery housing chamber comprises a first elongated resilient member and a second elongated resilient member arranged along a circumferential direction of the first cylindrical battery housing chamber,
the plurality of notches in the side wall of the first cylindrical battery housing chamber includes a common notch, and the plurality of notches in the side wall of the second cylindrical battery housing chamber includes the common notch, and
the plurality of elongated resilient members of the second cylindrical battery housing chamber comprises a third elongated resilient member located in the common notch and arranged, in a front view of the cylindrical battery housing case, at an intermediate position between the first elongated resilient member and the second elongated resilient member in the circumferential direction of the first cylindrical battery housing chamber.

### Claim 2 (depends on 1)

The cylindrical battery housing case according to claim 1, wherein the side wall of each of the cylindrical battery housing chambers extends in an axial direction in which the cylindrical battery is inserted into the cylindrical battery housing chamber,
wherein the notches extend along the axial direction from an end of the side wall, and
wherein the elongated resilient members are supported at the bottoms of the notches in the cantilevered manner and extend in the axial direction.
