Claims

[Scope of utility model registration request]

The first
A brake caliper 4 is provided with second friction pads 3 ₁ , 3 ₂ and first and second pinch arms 5 ₁ , 5 ₂ sandwiching both friction pads 3 ₁ , 3 ₂ in the circumferential direction of the brake disk. Both ends of the first friction pad 31 are provided on a bracket 6 fixed on the outer periphery of the brake disc 1 via sliding pins 11 so as to be slidable in the direction of the rotational axis c of the brake disc ₁ . It has a pressing center _O1 at the center position in the circumferential direction, and its first friction pad 3
₁ is provided on the first pinch arm 51, and the braking torque bearing portion 40 of the first friction pad ₃₁ is provided on the bracket ₆ , and the second friction pad 32 is provided with a pressing member 45 for pressing the brake disc 1 on the brake disc _1. A braking torque bearing part 41 is provided on each of the brake calipers 4, and intersects with a first straight line _l1 passing through the pressing center _O1 and the brake disc rotation center _O3 on one side of the brake disc 1, and Brake disc rotation center O than pressure center O ₁
on the second straight line _l2 existing on _{the third} side, and on the first
In the reaction force disc brake, a pair of fixing points _O2 _of the bracket 6 to the fixing member 7 are arranged on both sides of the straight line _l1 , respectively. A reaction force type disk characterized in that it is disposed in a region from the second straight line l2 to a third straight line _l3 that runs parallel to the second straight line _l2 and passes through the pressing center _O1 _. brake.
