PROBLEM TO BE SOLVED: To provide a multi-point stopper which is small-sized, is low in costs and is large in bearing-capacity. SOLUTION: When a plurality of stopper rods 1 charge an air-cylinder 7, an energizing lever 12 is rotated, pressurizing force between cylindrical rollers 4 is lost, also the pressurizing force of the rods 1 is lost and the rods are lifted to the upper end by spring force. When a work is mounted on the rods 1, the rods are pushed down to positions fitting for the shape. When the cylinder is discharged in such a state, a movable plate is narrowed, cylinder rods are fixed and, thus, the multi-point stopper which imitates the work shape is made.
