PROBLEM TO BE SOLVED: To improve the operability of a brake and the braking feeling by selecting a mode to brake only a front wheel and a mode to simultaneously brake front and rear wheels. SOLUTION: When a first brake lever 47 is turned, a first knocker part 10 of a first brake arm 6 is turned counterclockwise through a first Bowden wire 42, and a second arm part 9 of a second rake arm 7 is turned clockwise. When the first knocker part 10 is turned, a first relative turn regulating means 33 is engaged to turn the first arm part 8, a front wheel 2 is singly braked by first and second brake shoes 14, 15. When a second brake lever 49 is turned, the operating force is distributed by an equalizer lever 51, and the front wheel 2 is braked similarly to a single case through a second Bowden wire 38, and a rear wheel is braked through a third Bowden wire 52.
