PROBLEM TO BE SOLVED: To suppress crack initiation by suppressing orientation of a reinforcement material in a resin pipe joint mixed with the reinforcement material.SOLUTION: The pipe joint 10 includes: a tubular body part 12 integrally formed of a resin mixed with the reinforcement material 18; a torque input part 14 continuously connected to the body part 12 and having a cross sectional area in a radial direction of the body part 12 that is larger than that of the body part 12; and an intermediate thick wall part 16 swollen from the body part 12 in the radial direction of the body part 12, continuously connected to the torque input part 14 and having a cross sectional area in the radial direction of the body part 12 that is smaller than that of the torque input part 14 but larger than that of the body part 12.SELECTED DRAWING: Figure 1 |
