Definitions

  • the non-abutment region may be formed on both sides in the axial line direction with respect to the insertion end portion.
  • the insertion end portion in the abutment region, may abut the inner peripheral surface of the suction port in an elastically deformed state.
  • the cross-sectional shape of the first connecting portion 43A gradually changes from an elliptical shape to a circular shape, from the insertion end portion 42 side to the suction pipe main body 41 side. More specifically, in the first connecting portion 43A, the length of the elliptical shape in the minor axis direction gradually increases from the insertion end portion 42 side toward the suction pipe main body 41 side to coincide with the dimension of the elliptical shape in the major axis direction. As illustrated in FIG. 4 , the outer peripheral surface (an extending portion outer peripheral surface 43b) of the extending portion 43B abuts the suction port inner peripheral surface 32 over the entire circumference.
  • the second connecting portion 43C is connected to the other side of the extending portion 43B.
