Abstract
A sealing structure for a cylindrical body has an O-ring holder in which a planar O-ring that provides a seal in the planar direction and a radial O-ring that provides a seal in the axial line direction of the cylindrical body are incorporated in the crossing direction provided at both end parts of the cylindrical body; a pressing means for pressing the O-ring holder in the axial line direction of the cylindrical body via a pressing lid; the O-ring holder is pressed against a tube sheet of the fluid chamber via the pressing lid by the pressing means to press the planar O-ring onto the tube sheet, whereby a fluid tight seal is provided between the fluid chamber and the outside; and the radial O-ring is pressed onto the outer periphery of the cylindrical body to provide a fluid tight seal between the fluid passage and the fluid chamber.
