PROBLEM TO BE SOLVED: To obtain good effectiveness of braking by optionally adjusting an initial value of sandwiching force in response to a kind of a wheel and a bicycle, without changing a clearance between the rim and brake shoes. SOLUTION: A caliper type brake produce braking force by sandwiching the rim 4 of the wheel from the left and right, and has an expanding mechanism 14 for pushing the brake shoes 11R and 11L against the rim 4 by rocking arm parts 10R and 10L so that an upper end part mutually expands to open when towing a wire 40a, wherein this expansively opening mechanism has a pipe body connecting part 41 connected with a pipe body 40b, a wire connecting part 42 connected with the wire and a multi-node link 43 for connecting both connecting parts and the upper end part of the arm parts and expanding the upper end part of the arm parts by towing of the wire, and provides a brake 1 for the bicycle for arranging an adjusting mechanism 70 for adjusting an angle of a connecting body 90 to the wire in a state of maintaining a part between the rim and the brake shoes constant between the arm parts and the multi-node link.
