Claims (1)

[Claims for Utility Model Registration] (1) A joint body that receives one end of a conduit inside, a tightening nut that has an opening through which the conduit is inserted and is screwed into the joint body, and an annular one. A synthetic resin sealing body with a substantially triangular cross section, which is in the shape of a ring cut at two points, and is placed between one end surface of the joint body through which the conduit is inserted, and the inner end surface of the tightening nut opposing this. A conduit joint characterized by having: (2) The seal body has an annular contact piece with a square cross section that projects outward in the radial direction, and an annular inclined piece that extends outward in the width direction from the contact piece in a wedge shape, and one side surface of the contact piece is 2. The electric conduit joint according to claim 1, wherein the joint body is in pressure contact with one end surface, and the other side surface is in pressure contact with the inner end surface of the tightening nut. (3) The inner peripheral surface of the opening of the tightening nut has an annular slope with an angle complementary to the outer surface of the inclined piece of the seal body, and when the tightening nut is tightened, the inclined piece touches the annular slope of the tightening nut. 3. The conduit joint according to claim 1, wherein the joint is press-fitted into a gap between the surface of the conduit and the conduit surface to seal the gap. (4) Any one of claims 1 to 3, wherein the electric conduit has a soft synthetic resin coating layer on its outer periphery, and the seal body has an annular recess into which the coating layer bites into a surface in contact with the coating layer. Fittings for electrical conduits described in . (5) the annular recess has a substantially trapezoidal cross section with an inner surface inclined substantially parallel to the outside of the inclined piece;
5. The electrical conduit joint according to claim 4, wherein the inclined piece is entirely thin-walled. (6) Screwing an inner ring onto one end of a conduit inserted through a tightening nut having an opening for insertion of the conduit and a synthetic resin seal body having a generally triangular cross section cut at one point in the annular shape; This middle ring is housed in the joint body, and by tightening the tightening nut to the joint body, the seal body is brought into pressure contact with the outer peripheral surface of the conduit and the end face of the joint body and/or the middle ring, and the seal body is A joint for electric conduit, characterized in that the edge is press-fitted into the gap between the opening of the tightening nut and the surface of the electric conduit, and the gap is sealed. (7) A synthetic resin sealing body with a substantially triangular cross section, consisting of a ring cut at one point. (8) The seal body according to claim 6, comprising: an annular contact piece having a rectangular cross section that projects outward in the radial direction; and an annular inclined piece extending outward in the width direction from the contact piece. (9) The seal body according to claim 6 or 7, which is formed by cutting one part of the annular shape into a dogleg shape. (10) The seal body according to any one of claims 6 to 8, having an annular recess on the bottom surface.
