Ž<P>SOLUTION: The jack pin is provided with: a bar-like jack pin body 10, which pushes a work; a pin case 20, which houses the jack pin body 10; a spring 30, which is arranged in the pin case 20 and energizes the jack pin body 10 so that the jack pin body 10 is pushed out from the pin case 20; and an outer-case 40, which houses the pin case 20 partially from the edge of the pin case 20. The pin case 20 has, on its base end side, an outer-case fitting male screw 20A, and has, on its front end side from which the jack pin body 10 protrudes, a die mounting male screw 20B. The outer-case 40 has, in the inside area in which the pin case 20 is housed, a female screw 40A to be screwed with the outer-case fitting male screw 20A. The whole length of the jack pin is adjusted by adjusting the screwed-in amount of the pin case 20 into the outer-case 40. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
