A hand operated pulling and lifting hoist includes: a change gear that engages with a switching pawl fitting provided for an operation lever to convert a manual force applied to the operation lever into a hoist driving force; a fixed support ring disposed for the rotatable mounting of the operation lever about a driving member that is set about the drive shaft to transmit the hoist driving force to the drive shaft; a pivotable support ring formed on the operation lever and rotatably fitted to an internal circumference of the fixed support ring; and a driving-member contact prevention part on the change gear to prevent contact between the pivotable support ring and the driving member.
