Document Type and Number:
WIPO Patent Application WO/2019/220857
Kind Code:
A1
Abstract:
The present invention enables simpler and more reliable attachment of a joint guide (37) to a tube connection hole (31a, 31b) of a joint body (30) by means of press fitting the joint guide. On the inner periphery of the tube connection hole (31a, 31b) formed in the joint body (30), a plurality of abutting walls (42) are formed at equal angle intervals around a center axis (L) of the tube connection hole (31a, 31b) so as to extend along the center axis (L). The joint guide (37) is cylindrical, and has an inverted hook (37e) on its outer periphery. When the joint guide (37) is press-fitted into the tube connection hole (31a, 31b), the outer peripheral surface of the joint guide (37) abuts inner wall surfaces (42a) of the abutting walls (42), and the inverted hook (37e) is locked to the abutting walls (42).
