Synthetic resin-made fastening-limiting device for a joint fastening member |
摘要 |
The present invention relates to a fastening-limiting device for a fastening member which fastens a pipe inserted into a pipe receiving port on the side of a joint. The fastening-limiting device has a ring portion which is fittable onto the outside of the pipe receiving port. A beam portion is formed on the ring portion. A protrusion is formed on the beam portion. A first abutting portion which is to abut against a reference face on the side of the joint is formed on one end of the ring portion. A second abutting portion which is to abut against a confronting portion of the fastening member is formed on the other end of the ring portion. A gap between the first and second abutting portions and is equal to the gap between the reference face and the confronting portion at the time when the fastening member exerts a sealing property and a function of preventing slipping-off. According to the present invention, when an appropriate sealing property of the pipe connection portion and prevention of slipping-off of the pipe are to be attained, the screw amount of the fastening member can be appropriately determined without dispersion.
