To provide a technique for stably pressing a stopper that stops rotation of a rotary table (121). An injection molding machine (10) includes the rotary table (121), a block (510A, 510B, 510C), a stopper (520), and a pressing member (530). A die is attached to the rotary table (121). The block ( 510A, 510B, 510C) is provided in the rotary table (121) . The stopper (520) is pressed against the block (510A, 510B, 510C) to stop rotation of the rotary table (121). The pressing member (530) presses the stopper (520) from a side opposite to the block (510A, 510B, 510C), when the block (510A, 510B, 510C) is pressed against the stopper (520). The pressing member (530) presses the stopper (520) on both sides of the rotary table (121) in a radial direction across a movement locus of the block (510A, 510B, 510C) .
