PROBLEM TO BE SOLVED: To provide a battery pack module which allows smooth insertion of a cylindrical battery into a retention hole, while improving static retention force for the cylindrical battery and its vibration resistance.SOLUTION: A battery pack module 1 is configured such that a plurality of cylindrical batteries 3 arranged in parallel to each other are retained in a battery retention spacer 2. The battery retention spacer 2 has a plurality of retention walls 21 each provided with, in the inner circumference, a retention hole 211 in which each of the cylindrical batteries 3 is retained. The retention walls 21 are annularly formed around the cylindrical batteries 3 and have elastic deformation parts 22, at a plurality of locations in a circumferential direction C of the cylindrical batteries 3, for enhancing the elastic deformation in a radial direction R of the cylindrical batteries 3. |
