Abstract

See full text

There is provided a pipe joint structure wherein a proximal insert portion (20a) of an attachment pipe (20) is inserted into and secured to a base pipe (12). This pipe joint structure comprises: a cylindrical rotational operating member (30) rotatably and externally fitted on the base pipe; and a pin-shaped projection (25) which is radially protruded from the proximal insert portion of the attachment pipe; wherein the rotational operating member is provided, on an inner circumferential surface thereof, with a spiral pulling/pushing groove (35) enabling the pin-shaped projection to be introduced therein through a cut-out portion (16) formed at a distal portion (12a) of the base pipe, thereby enabling the attachment pipe to be pulled into the base pipe through the displacement of the pin-shaped projection along the groove as the rotational operating member is rotated in one direction and enabling the attachment pipe to be pushed out of the base pipe through the displacement of the pin-shaped projection along the groove as the rotational operating member is rotated in the opposite direction.
