<p><P>PROBLEM TO BE SOLVED: To provide a tube mounting structure allowing positions in the axial direction and the rotating direction of a tube to be fixed with excellent work efficiency; a tube; and a clamp. <P>SOLUTION: This tube mounting structure 10 includes the tube 1 having a plurality of projecting parts on its circumference 40, and a clamp 2 fixing the tube 1. The tube mounting structure is characterized in that the tube 1 includes annular projecting parts 11 each having a first outer diameter R1, and annular small-diameter projecting parts 12 each having a second outer diameter R2 smaller than the first outer diameter R1 and having a flat part A (12Ya) in a part between two annular projecting parts 11i and 11j in the axial direction of the tube 1; and the clamp 2 is structured that the width L2 of an arm part 22 for mounting the small-diameter projecting part 12 thereto is nearly equal to the distance L1 between the two annular projecting parts 11i and 11j, and has, in the arm part 22, a flat part B (2a) facing the flat part A (12Ya). <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
