A mating type bracket in which a pair of frame plates are fastened with a plurality of bolts, the front frame portion held by the front bolts is provided with a buffer member, and the front frame portion including the buffer member is provided with a buffer member. The width of the entire frame is larger than the width of the breaker body in the tightened position when not tightened.
By compressing the buffer member in the axial direction so that the width is approximately equal to the width of the breaker body when tightening the bolts, the expansion of the buffer member in the peripheral direction suppresses the breaker body and prevents the breaker from swinging back and forth. Matching type bracket for breaker to prevent. 2. The bracket according to claim 1, wherein the rear frame portion held by the back bolt also includes a buffer member. 3. Claim 1: The buffer member is made of urethane resin, hard rubber, or felt sheet with high compressive strength.
Brackets listed. 4 U welded rectangular stay with center through hole
A rectangular shock absorbing member having a cover with a letter-shaped cross section and a central through hole is placed on each side of the stay and covered with the cover, and a pair of shock absorbing members and a front bolt passed through the through hole of the stay are connected to each other. Front frame for the bracket held between the frame plates.
