Document Type and Number:
WIPO Patent Application WO/2022/209537
Kind Code:
A1
Abstract:
[Problem] To provide a piping member that makes a shaft section of a handle mechanism less likely to be damaged even if a large impact is applied to a handle. [Solution] A handle mechanism 14 of this piping member comprises: an inner member 30 that is rotatably attached to a piping body 12 and is connected to a valve member within a fluid channel of the piping body 12; an outer member 32 that is rotatably disposed on the outer side of the piping body 12; and a linking pin 48 that links a first linking end section 42 of the inner member 30 and a second linking end section 46 of the outer member 32 in a rotation direction. The piping body 12 has a support surface 60a that is located on the periphery of the second linking end section 46. When a force acts on the outer member 32 in a direction so as to cause the outer member 32 to pivot around a pivot axis N1, the second linking end section 46 engages with the support surface 60a so that the outer member 32 is supported by the piping member 12 in the pivoting direction.
