First Claim
1. A pipe joint for connecting a first pipe member and a second pipe member such that a portion of the first pipe member is disposed inside of a portion of the second pipe member, the first pipe member and the second pipe member including a first engaged part and a second engaged part, respectively, the pipe joint comprising:
- a pipe mounting portion capable of mounting to one of the first and second pipe member;
an engagement portion including a first contact portion for contacting the first engaged part of the first pipe member and second contact portion for contacting the second engaged part of the second pipe member, the engagement portion capable of being disposed in the portion of the second pipe member for engaging with the first pipe member and the second pipe member; and
an elastic displacing portion connecting the pipe mounting portion and the engagement portion, the elastic displacing portion supporting the engagement portion to allow displacement of the engagement portion with respect to a radial direction of the second pipe member;
whereinthe first contact portion is a step portion that is provided at the tip end of the engagement portion; and

Abstract
A pipe joint for coupling a first pipe member and a second pipe member has a pipe mounting portion, an elastic displacing portion and an engagement portion. The pipe mounting portion is configured to be attached to one of the first and second pipe members. The elastic displacing portion connects the pipe mounting portion and the engagement portion and allows the engagement portion to displace in a radial direction. The engagement portion has a first contact portion for contacting a first engaged part of the first pipe member and a second contact portion for contacting a second engaged part of the second pipe member.
