Abstract: In a work assisting apparatus helping workers to lift heavy objects with hands, their work is assisted with a light-weight and simply configured winding device, contributing to cost and load reduction while refraining a belt as a support wire rope from hindering their normal working behavior, or another objects from being caught in or wound around the belt, the work assisting apparatus including: a fitting portion fitted on a torso, a wearing portion worn on an arm or a hand of a worker, a belt with one end portion combined to the wearing portion, and a winding device coupled to the fitting portion and winding another end side of the belt. The winding device includes a lock mechanism locking a draw-out position of the belt so as to restrict further drawing out when drawing the one end portion.

Abstract: In a torque convertor including a pump impeller, a turbine runner and a stator, an outer regulation surface facing inwards in a radial direction is provided at a turbine shell on an inward side in the radial direction from a turbine blade, an inner regulation surface that approaches and faces the outer regulation surface from inside in the radial direction is provided at a stator hub, and at least one of the outer regulation surface and the inner regulation surface is formed into a ring shape. Accordingly, movement of the stator along the radial direction at a time of transportation is inhibited and it is made unnecessary to form flange portions at core rings of the pump impeller and the turbine runner.
