Abstract

PROBLEM TO BE SOLVED: To prevent stress, deformation, and crack being applied to a train wheel and a tenon part from being bent by providing a plurality of projecting parts at a part than flatly overlaps with a battery for securing a gap between a part of retaining the train wheel and its surrounding and the battery and allowing the projecting parts to receive the battery. SOLUTION: A projecting part 11 is provided at a plurality of parts for receiving the reverse side of a battery 1 so that a gap A is secured between a part for retaining a train wheel 21 of a train wheel support 20 and the battery 1 at a main plate 10, thus preventing a part for retaining the train wheel 21 of the train-wheel support 20 from interfering with the battery 1 of a tenon part 21a and hence preventing stress being applied to the train-wheel support 20 when incorporating the battery 1 and hence preventing the deformation and the crack of the train-wheel support 20 and the bending of the tenon part 21a of the train-wheel 21. Since the projecting part 11 is provided at a plurality of parts, the lower surface of the projecting part 11 becomes the train-wheel support stand of the main plate 10, thus preventing the tenon part 21a and its surrounding from interfering with the battery 1 and hence preventing the stress being applied to the train-wheel support 20 and the deformation and crack of the support 20 and the bending of the tenon part 21a.
