FIELD: machine building.
SUBSTANCE: invention relates to handle for turning of rod-like or tubular rotating body, and also screw jack and manufacturing method of such handle. Handle contains implemented in parallel convexity axis, forming around axis, at least partly cavity. Convexities are located in turn one by one lengthwise axis. At least one convexity is moulded relative to neighbouring convexity radial oppositely relative to axis. Screw jack contains rotating body. On rotating body it is proposed handle. Convexities of handle are implemented with ability of meshing with rotating body by pressure of steel strip by means of forming operation device, allowing first and second deforming bodies. First and second deforming bodies allows moulding elements, passing in opposite directions. Moulding elements allows essentially corresponding convexities handles of mould. Convexities of handle are formed in steel strip at one operation ensured by pressure to each other of deforming bodies.
EFFECT: there is reduced materials consumption and labour coefficient.
