PURPOSE:To store large amount of energy while enabling freely storing/taking- out through different I/O terminals by storing rotary energy into winding force of self-winding molded spring band and utilizing storing capacity in longitudinal direction. CONSTITUTION:Rotation of a wheel 5 where the outer end section 11 of self winding spring 10 wound around a spool 7 is fixed to a portion of circumference is blocked by a stopper click 12 and a ratchet 12' to rotate the spool 7. When removing said click 12, the stored force can be taken out from its shaft 6 through rotation of wheel 5 in arrow direction. Even under provision of input M, it can be taken out as outputs M1, M2. Since said spring 10 has winding resiliency because the winding portion is molded, it is uniform in longitudinal direction to increase the storing amount of force. Upon rotation of wheel 5 in counter-arrow direction, it will function as brake to enable storing of said force in storing direction. |
