Title:
METAL PIPE SHAPE NUT
Document Type and Number:
Japanese Patent JP3389189
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To solve such a problem that a metal round bar type nut increases in its cost and a working ability in mounting operation is reduced because the metal round bar type nut increases in its weight as its outer diameter increases.
SOLUTION: Inside a metal pipe having an inner diameter smaller than a distance between opposite sides of a hexagon or square nut, a fixing position is provided in which a distance between the opposite sides of the nut is ensured. In this position, the nut is sealed such that a direction of a screw hole of the nut is perpendicular to the axial center direction of the metal pipe, and the metal pipe is formed with a bolt insertion hole which communicates with the screw hole of the nut.
