摘要:PURPOSE:To assure braking operation even when a lightweight load L is handled. CONSTITUTION:A spring member 18 which energizes a driving member 16 in hoisting direction relative to an input shaft 11 is provided. Since a torque due to the spring member 18 is applied to the drive member 16 even if a load L is light, a ratchet wheel 13 can be always restricted by a required and sufficient force.
