PROBLEM TO BE SOLVED: To provide a game ball hoisting polisher which enables the simple and quick mounting of an energizing means such as a coil spring on the guide rail and makes the energizing means hard to slip off, hence requiring no precaution in handling and also enables the re-mounting thereof on the spot even when it comes off. SOLUTION: A mounting part 530 which is made engageable with one end side of the coil spring 53 to match the shape of the terminal on the one end side thereof is provided on the rear side of the guide rail 51 and the coil spring 53 is mounted on the guide rail 51 by getting the one end side of the coil spring 53 engaged with the mounting part 530. The guide rail 51 is supported being advanceable or retractable on the side of the hoisting belt 25 within a guide frame 52 while the other end side of the coil spring 53 mounted on the rear side thereof elastically contacts the inner wall of the guide frame 52.
