A shot-blasting machine for shot blasting a workpiece is disclosed. The shot-blasting machine comprises a rail 2 mounted on an upper part of the shot-blasting machine and extending in a horizontal direction, one or two hoists movable along the rail, and two inverting mechanisms 4. Each inverting mechanism 4 includes chain slings 1 for supporting one workpiece W at one end or the other end such that the workpiece W is suspended therefrom and includes a feeder for feeding the chain sling 1. An enclosure B in the shot-blasting machine has an entrance at one side and defines a projecting chamber 5 therein. The upper surface of the enclosure B is provided with an elongated opening 51. The volume of the projecting chamber 5 is to allow the workpiece W supported by the chain slings 1 to be moved along the direction that the rail 2 extends by running the hoist 3, while the workpiece W can be rotated about a rotating axis that is parallel to the direction that the rail 2 extends. The upper surface of the enclosure B is provided with a sealing mechanism 6 for preventing the shots from dispersing from the opening 51 by closing the opening 51 in which the chain slings 1 are inserted.
