<p>PURPOSE:To securely position a housing between flanges and prevent a shaft from coming into direct contact with pressure with both sides of the housing by interposing a thin guide piece having elasticity between a flange part of a body case and the housing of a lid case. CONSTITUTION:A guide plate 25 is provided on a main body frame 13 according to an upper part of a pressing board 17 so that a lid case 5 to be carried in is guided toward the pressing surface of the pressing board 17. Hanging arms 31a are mounted on both ends of a mounting part 31 so that they are positioned on both sides of a main body case 3, while each hanging arm 31a is provided in a V-shape with a guide piece 33 with its base end located outside a flange part 3d of the main body case 3 and with its tip located inside a flange 3b. This guide piece 33 is formed of a stainless steel board for example which is thin and has elasticity. The guide piece 33 is moved along with operation of a third cylinder 29 between a lower position toward the flange part 3d according to a shaft part 3c and an upper position off the flange part 3d.</p> |
