The pipe member 29 is integrally connected by a connecting portion 30 using a connecting sleeve 39, a notch ring member 35, a button member 37, and the like.

  In order to connect the pair of pipe members 29 by the connecting portion 30, the connecting sleeve 39 is attached to the female side end portion 29 b of the one pipe member 29, as shown in FIGS. The connecting sleeve 39 is provided with an annular belt groove 40, a protrusion engaging hole (protrusion insertion hole) 43a, a positioning guide rib 42, and the like. Further, the connecting sleeve 39 can be elastically deformed so that the diameter can be increased, for example, by forming a cut in the axial direction. The connecting sleeve 39 has a protrusion engaging hole (protrusion insertion hole) 43 a formed in the annular band groove 40, and a protrusion engaging hole (protrusion insertion hole) 43 b formed in the female side end portion 29 b of the pipe member 29. At the same time, the positioning guide rib 42 disposed on the opposite side in the radial direction from the projection engaging hole (projection insertion hole) 43a is inserted into the positioning locking hole 44 formed in the female side end portion 29b of the pipe member 29. It is locked and attached to the female side end portion 29 b of the pipe member 29. As a result, the positioning guide rib 42 protrudes inward from the inner peripheral surface of the female side end portion 29b.

  Further, the notch ring member 35 and the button member 37 are attached to the connecting sleeve 39. That is, the notch ring member 35 pushes and expands the notch 35a and elastically deforms the notch 35a so that the engaging protrusion 36 that protrudes inward from the inner side surface at the center upper portion is aligned with the protrusion engaging hole (protrusion) of the matching connecting sleeve 39. The insertion sleeve 43a is engaged with the projection engaging hole (projection insertion hole) 43b of the female side end 29b so as to be fitted into the annular groove 40 of the connecting sleeve 39. As a result, the distal end portion of the engagement projection 36 is formed from the inner peripheral surface of the female end portion 29b of the pipe member 29 in a state where the tapered surface 36a provided at the distal end portion is directed toward the opening side of the pipe insertion hole 38. It is arranged to protrude inward.

  The button member 37 is, for example, a plastic molded product having an elliptical flat shape whose outer peripheral surface is a gently curved surface, and includes a pair of extruded leg portions 37a. The button member 37 locks the pushing leg portion 37a in a locking groove 35b provided in a portion continuous with the cutout portion 35a of the cutout ring member 35, and an annular belt groove 40 in the region of the cutout portion 35a.

  The male end 29a of the other pipe member 29 connected to the female end 29b of one pipe member 29 is reduced in diameter so that it can be inserted into the pipe insertion hole 38 of the female end 29b. . The male side end 29a has a projection engagement hole (projection insertion) that can be matched with the projection engagement hole (projection insertion hole) 43b of the female side end 29b and the projection engagement hole (projection insertion hole) 43a of the connecting sleeve 39. Hole) 43c is formed. Further, a guide groove 45 is formed in the male end portion 29a so as to be disposed radially opposite to the protrusion engaging hole (projection insertion hole) 43c and to extend in the axial direction from the edge portion of the male end portion 29a. Has been.

  As shown in FIG. 8A, the other pipe member 29 is directed toward the pipe insertion hole 38 of the female side end portion 29b of the one pipe member 29 to which the connecting sleeve 39 and the notch ring member 35 are attached. The male side end portion 29a is inserted. As shown in FIG. 8B, this insertion operation is performed by a guide groove provided in the positioning guide rib 42 protruding from the inner surface of the female end portion 29b and extending in the axial direction on the male end portion 29a. By locking and guiding 45, it is possible to perform smoothly in a stable state while positioning.

  Further, after the male side end portion 29a is inserted until the edge of the tip end of the male side end portion 29a abuts on the tapered surface 36a of the engaging projection 36 protruding from the inner side surface of the female side end portion 29b, the male side end portion 29a is further inserted. The end 29a is inserted. As a result, the tapered surface 36a of the engagement protrusion 36 rides on the edge of the distal end of the male end portion 29a, whereby the notch ring member 35 is expanded in diameter and the engagement protrusion 36 is pushed up.

  As shown in FIG. 8C, the protrusion engagement hole (protrusion insertion hole) 43c of the male end portion 29a is the protrusion engagement hole (protrusion insertion hole) 43b of the female end portion 29b and the protrusion of the connecting sleeve 39. When the male end portion 29a is inserted until it matches the engagement hole (projection insertion hole) 43a, the engagement projection 36 is pushed down by the biasing force toward the inside of the notched ring member 35 in the expanded state. When the engaging protrusion 36 is pushed down, the matching protrusion engaging hole (protrusion insertion hole) 43c of the male end part 29a, the protrusion engaging hole (protrusion insertion hole) 43b of the female end part 29b, and the connecting sleeve 39, the engaging protrusion 36 is simultaneously inserted into and engaged with these protrusion engaging holes (protrusion insertion holes) 43a, 43b, 43c. . As a result, the pair of pipe members 29 are firmly connected by the overlapped male end portion 29a and female end portion 29b.

  In the present embodiment, when the engagement protrusion 36 is simultaneously inserted and engaged in the protrusion engagement holes (projection insertion holes) 43a, 43b, and 43c, the male side having a reduced diameter is formed at the opening peripheral edge portion of the female side end portion 29b. Since the base end portion 46 of the end portion 29a comes into contact, the opening peripheral edge portion of the female side end portion 29b is supported by the base end portion 46, and the pair of pipe members 29 can be connected in a more stable state. It becomes possible.

  Moreover, in this embodiment, in order to cancel | release the connection state of a pair of pipe member 29 connected by the connection part 30, as shown in FIG. 9, the clearance gap 47 (refer FIG. 8) between the annular belt grooves 40 is shown. ), The button member 37 is pressed. By pressing the button member 37, the notch ring member 35 expands the notch 35a by the pushing force through the pushing leg 37a locked in the locking groove 35b (see FIG. 7). It is pushed outward along the outer peripheral surface of the annular belt groove 40. When the notch ring member 35 is pushed outward, the engagement protrusion 36 is disengaged from at least the protrusion engagement hole (protrusion insertion hole) 43c of the male side end portion 29a. In this state, the male side end portion 29a is extracted from the female side end portion 29b, and the connection state of the pair of pipe members 29 can be easily released.

  In addition, according to the structure of the connection part 30 of this embodiment, the positioning guide rib 42 and the guide groove 45 which guide insertion of the male side edge part 29a to the female side edge part 29b are protrusion engagement holes (projection insertion holes). ) 43a, 43b, and 43c are provided in a portion on the opposite side to the radial direction apart from these in the circumferential direction, so that the male side end 29a can be inserted in a more stable state. The positioning guide ribs 42 and the guide grooves 45 do not have to be provided in a portion on the opposite side in the radial direction as long as the positioning guide ribs 42 and the guide grooves 45 are separated from the protrusion engagement holes (projection insertion holes) 43a, 43b, 43c in the circumferential direction. Further, by this, the protrusion engaging groove (protrusion insertion hole) 43c of the male end portion 29a and the protrusion engagement hole (protrusion insertion hole) 43b of the female end portion 29b are provided with protrusion guide grooves that are continuous with these peripheral portions. Since there is no stepped portion due to the projection guide groove or the like at the peripheral edge of the opening of the projection engaging holes (projection insertion holes) 43b, 43c, the engaging projection 36 is provided via such a stepped portion. It is possible to effectively avoid the tendency to come off.
