PROBLEM TO BE SOLVED: To accomplish miniaturization and weight reduction by simplifying the structure of a regeneration brake. SOLUTION: When a brake pedal is stepped, a brake oil pressure-on-switch is operated, a solenoid clutch 12 and a brake caliper 9 are operated, a spiral spring retaining rotor 11 is connected to a spiral spring gear shaft 6, the spiral spring retaining rotor 8 is fixed, a brake oil pressure-off-switch simultaneously becomes in the disconnection state, operation of a brake caliper 13 is stopped, the spiral spring retaining rotor 11 is rotated with the spiral spring gear shaft 6 and rotation energy of a drive shaft 1 is accumulated on the spiral spring 10. At starting and acceleration, the energy accumulation on the spiral spring 10 is returned to the spiral spring gear shaft 6 and the drive shaft 1 from the spiral spring retaining rotor 8 through a one-way clutch 7 and assist it.
