Claims

[Scope of utility model registration request]

(1) In a passage closure structure in which the passage is closed by a plug disposed in the middle, a hole is opened in at least one end surface of the plug, and an expansion jig is press-fitted into the hole, and the plug is closed. A passageway closing structure characterized in that the structure is expanded and a part of the outer circumference is pressed against the inner circumference of the passageway.

(2) The closing structure according to claim 1, which is a registered utility model, characterized in that the outer circumferential surface force of the pressing portion of the plug is an annular uneven surface.

(3) Claim 1 of the Utility Model Registration Claim, characterized in that the expansion jig is a shaft body formed at one end with a tapered portion having a tip portion having a smaller diameter than the inner diameter of the open end of the hole portion, or The passageway closure structure described in Section 2

(4) A passage closing structure according to claim 1 or 2 of the utility model registration claim, characterized in that an adhesive is interposed between at least a part of the outer circumference of the plug and the inner circumference of the passage. .
