PURPOSE: To provide a game ball lifter which prevents the curving of soft bodies by thermal expansion, improves the elasticity of the soft bodies and prevents the partial wear of the soft bodies during lifting of the game balls. CONSTITUTION: This game ball lifter has an openable and closable door 66 which is arranged to face a lifting belt 25 and the soft elastic bodies (soft bodies) 25 which are arranged at this door 66 and hold pinballs PB between this door and the lifting belt 25 and impart lifting force thereto. The soft elastic bodies 71 are so arranged that spacings D are formed between the flanks 71A of the soft elastic bodies 71 and guide rails 74 facing these flanks 71A when the projections 72 of the soft elastic bodies 71 are arranged with the rising part 74A of the guide rails 74 of the upper door 66. Plural contact parts 73A parted from each other are formed on the surfaces of the soft elastic bodies 71 facing the door 66. Guide surfaces 73c which prevent the interference of the pinballs PB with the guide rails 74 by limiting the moving quantity at which the pinballs move in a transverse direction are formed at the soft elastic bodies 71. |
