1. A battery pack, comprising:
- a plurality of battery cells;
a battery holder configured to receive the plurality of battery cells, wherein the battery holder comprises;
at least a first battery cell receiving section and a second battery cell receiving section; and
a projection between the first battery cell receiving section and the second battery cell receiving section; and
a battery receiving case configured to receive the battery holder,wherein an inner surface of the battery receiving case comprises a deformation section that comes into contact with the projection, andwherein the deformation section comprises;
a first protrusion;
a second protrusion,wherein the first protrusion and the second protrusion are bent so that a first end surface of the first protrusion faces a second end surface of the second protrusion;
a facing gap between the first protrusion and the second protrusion; and
a cavity section that communicates with the facing gap, wherein the first protrusion and the second protrusion are elastically deformable in a direction toward the cavity section.
