摘要： A battery spacer comprises: a cylindrical case body into which a battery is inserted; a bottom wall portion with which an anode-side end of the battery is to come into contact, the bottom wall portion having an anode exposure hole from which a negative terminal of the battery is partially exposed; an annular top wall member that is located opposite to the bottom wall portion 8 and has a central opening into which the battery is inserted; a plurality of anode-side catching pieces that have anode-side engagement hooks extending from the circumference of the anode exposure hole toward the interior of the case body and engaging with an anode-side outer peripheral surface of the battery, and hold the anode side of the battery; and a plurality of cathode-side catching pieces that have cathode-side engagement hooks extending from the circumference of a central opening toward the interior of the case body and engaging with a cathode-side outer peripheral surface of the battery, and hold the cathode side of the battery.

摘要： A battery spacer includes: a storage case having a bottomed cylindrical shape in which a battery is stored; a lid part which closes an opening of the storage case; and a positive electrode relay terminal which is provided to the lid part, a part of which protrudes from a top surface of the lid part, and which abuts on a positive electrode terminal of the battery in the storage case. The lid part has a protruding section formed which protrudes further to the battery side than a terminal contact surface at which the positive electrode terminal of the battery abuts on the positive electrode relay terminal. The protruding section has a protruding length h, in the axial direction of the battery, from the terminal contact surface, shorter than the length H of the positive electrode terminal of the battery, and has an annular shape having a diameter R that is larger than the diameter r of the positive electrode terminal of the battery and is smaller than the diameter S of the battery in the radial direction of the battery.
