<p>PROBLEM TO BE SOLVED: To make absorbable a distortion generated in a side surface plate, remarkably reduce transmission of the distortion to a welding part and additionally provide a sound preventing means, even when between the right/left side surface plates is connected by a mounting bolt. SOLUTION: This bracket comprises a bracket main unit 32 and a lower part front surface plate 50, the bracket main unit is formed in substantially box shape having an opening part 47 in one side between right/left side surface plates by assembling right/left side surface plates 33, 34, rear surface plate and a rear part cover plate 43 by a fusing means, in width narrow parts 33a, 34a of the light/left side surface plates serving as a tip end side of this bracket main unit, a plurality of mounting bolts 58 are inserted, insertion holes 36a, 36b fixing a breaker B are provided, between this breaker B and the width narrow part, a breaker fixing plate 48 fixedly fitted to the breaker B to have an insertion hole conformed to the insertion hole is interposed, in an opening part side of this width narrow part, the lower part front surface plate mounted with the breaker fixing plate to close partly the opening part is mounted, and a slit is provided in an substantially central lengthwise direction of the rear surface plate.</p> |
