Abstract
A tube-attached coupling structure is provided by using a piping coupling with good compatibility, workability and processability. A manufacturing method of the tube-attached coupling structure includes a step of preparing a photocurable gel-like body in a hollow cylindrical shape, a step of fitting the photocurable gel-like body in the attaching hole, a step of inserting an end portion of a connection tube into a hollow hole of the photocurable gel-like body, and a step of curing the photocurable gel-like body by irradiating the photocurable gel-like body with light.
Claims9
A manufacturing method of a tube-attached coupling structure in which a connection tube is attached to a base body having an attaching hole, the method comprising the steps of:
- preparing a photocurable gel-like body in a hollow cylindrical shape;
- fitting the photocurable gel-like body into the attaching hole;
- inserting an end portion of the connection tube into a hollow hole of the photocurable gel-like body;
- and
- curing the photocurable gel-like body by irradiating the photocurable gel-like body with light.
A tube-attached coupling structure comprising:
- a base body including an attaching hole;
- and
- a connection tube attached to the attaching hole by a photocurable resin,
- wherein the photocurable resin is a resin cured in a shape to close a gap between the attaching hole and the connection tube in a connection part.
