Claims

[Scope of utility model registration request]

A first radial step 24 is formed on the outer periphery of the end of one first pipe 21, and the first radial step 24 includes:
Elastic body 3 having tongue pieces 33 that elastically deform in the radial direction
An adapter 35 that can be inserted into the sleeve 29 is fitted onto the outer periphery of the end of the other second pipe 22, and the tongue piece of the elastic body 31 is attached to the adapter 35. 33 is locked, and the second radial step portion 39 of the tongue piece 33 on the elastic body 31 is caused by the rotational movement of the adapter 35.
A circumferential inclined portion 40 that releases the lock from the radial stepped portion 39 and a guide groove 4 formed in the sleeve 29.
3 is formed with a stopper protrusion 42 that is inserted at a predetermined rotational position of the adapter 35, and smooth sliding contact between the tongue piece 33 of the elastic body 31 and the circumferentially inclined part 40 is formed. A pipe joint structure characterized by forming a curved surface portion 33b.
