PURPOSE:To make the movement of a driven body smooth by eliminating the bending of the driven body, by a method wherein the driven body which is connected by a cam with a driving body performs reciprocation in a predetermined direction and performs reciprocation in the direction different from a moving a direction is provided and pressure receiving jig for a heat insulation box is transferred to a predetermined position based on a movement of the driven body. CONSTITUTION:When a driving body 21 is moved in the direction of an arrow 25, a driven body 27 is moved in the direction of an arrow 32 which is different from that of the driving body 21 by a cam mechanism 34. In this case, as the force of a direction of the arrow 25, that is, the moving force of the driving body 21 is received by a roller 49 of a receiving member 46, bending torque is not generated on the driven body 27 and rocking resistance to the receiving member 46 can be made extremely little. As an upper bracket 35 also moves integrally according to the movement of the driven body 27, a pressure receiving jig 43 is transferred to an opening part 7 by moving a connecting arm 39 in the direction of an arrow 42 by an auxiliary cam mechanism 40. In addition, in the case where the pressure receiving jig 43 is pulled out through the opening part 7, the driving body 21 is moved in the opposite direction of the arrow 25. |
