構造。[Claims for Utility Model Registration] (1) A shank body that is cylindrical as a whole and has an annular rib protruding inward on its lower surface, and is inserted into this shank body from above, and the outer periphery of the head is connected to the shank body. The lower edge of the outer periphery of the head engages with the rib, and the threaded portion protrudes downward from the center hole of the rib to hold the upper mold unit. A fixing bolt is screwed onto the base plate, and the fixing bolt is inserted through a spring into a plurality of holes drilled radially from multiple locations on the outer periphery of the head of the fixing bolt toward the center, and is protruded outward by the spring. 1. A shank structure in a press device, comprising: a plurality of balls biased to do so. (2) The shank structure in a press apparatus according to claim 1, further comprising a cylindrical body inserted into the shank body from above the fixing bolt. (3) The shank structure in a press apparatus according to claim 1 or 2, wherein a gap between the outer circumference of the fixing bolt and the inner circumference of the shank body is 1 to 1.5 mm.
