PROBLEM TO BE SOLVED: To provide the positioning structure of a knock pin that can separate a plurality of members assemble fix each mating face without damaging the knock pin for positioning and easily when assembling every member. SOLUTION: Besides a grooved part 18 is formed in each knock pin 15, an inflow channel 19 is formed to pump an air (fluid) on a ladder frame 13 into the grooved part 18 from outside. Therefore, each knock pin 15 transforms elastically under the fluid pressure of proper air when the air flows into the grooved part 18 through the inflow channel 19 from outside under the high pressure and the opening to allow the withdrawal of the knock pin 15 is formed between the knock pin 15 and the inner face 17a of each pin 17 hole of the ladder frame 13.
