<p>PROBLEM TO BE SOLVED: To provide a tightening band with a simplified constitution, a good productivity, a sure seal property of a member to be tightened, a good workability and handling property. SOLUTION: This band is formed in a ring shape in which both end sides of a metal made band member 2 are overlapped and has a tightening ear 3 folded outward in a gate shape and formed on the outside band part B of the overlapped part. The end part 2a of the inside band part A of the overlapped part is molded in a fork shape and hollows 8, 8 in which the fork shape end part 2a can be stored by bending the width direction both sides of the outside band part B outside are formed on the prescribed position of the outside band part B and the fork shape en part 2a is stored in the hollows 8, 8 by shrinking the diameter of the band member 2 formed in a ring shape by pressing and smashing the tightening ear 3.</p> |
