Patent attributes
A member-joining device with which, when pipe members etc. are fixed to each other, a sufficient fastening force can be obtained even if the members have thin wall thickness. Member-joining device 8 has a first bridge member, a second bridge member and drawing means 6. First bridge member 81 joins first member 5 having a pair of opposing walls 53, 53 and a second member 31 having a pair of opposing walls 311, 311 and is spanned at a predetermined position of the first member between the opposing walls 53, 53. Second bridge member 82 is spanned at a predetermined position of second member 31 between the opposing walls 311, 311. Drawing means 6 draws first bridge member 81 and second bridge member 82 in the direction where both members are closer to each other. Accordingly, first member 5 and second member 31 are pressed and joined to each other by a drawing force of drawing means 6.
