  • Patent number: 9543554
    Abstract: A battery holder includes restriction members protruded from a holding base plate in an axial direction of batteries to be located in spaces between the batteries. Each of the restriction members has: a tapered surface which is inclined to the axial direction and is in line contact with an outer periphery of the end face of the battery when the restriction member is inserted into the space, so as to apply a force to move the battery in a radial direction of the battery; and a support surface which supports a side face of the battery that is not in contact with the tapered surface, by surface contact. The support surface receives a moving force in the radial direction from the tapered surface and supports the side face of the battery by a reactive force.

  • Publication number: 20140283360
    Abstract: A battery holder holds a plurality of batteries by a simple structure. A battery holder 20 has a holder member 40 to hold batteries Bt. The holder member 40 includes a holder body 42 provided as a plate-like member, and holding holes 40S. The holding hole 40S is formed, such that a holding space 40Sa is secured between the inner wall of the holding hole 40S and the side face of the battery Bt. The holder member 40 has pressing projections 42a, each being formed by pressing and plastically deforming part of the holder body 42 toward an axial direction of the battery and formed by protruding part of the inner wall of the holding hole 40S toward the center of the battery. The pressing projections are arranged, such as to press the side face of the battery Bt and hold the battery Bt in the holder member 40.
