Abstract
(EN)
This disk brake device (100) is provided with: a pair of brake arms (13) that press a brake rotor (35) with a pad assembly (33)in a sandwiching manner; a pair of cam levers (15) each having one end (55) rotatably connected to respective cam holders (57) connected to one end section (23) of the respective brake arms (13), and the other end (59) rotatably connected to a rod (47); eccentric cams (17) that rotate the brake arms (13) by means of the rotation of the cam levers (15) connected through rotation center shafts (61) held in the cam holders (57); and a lever holding member (19) that guides the respective rotation center shafts (61) on a straight line (X) in the expansion direction of the pair of end sections (23).
