b 5 at even intervals and contacting portions 15 b 1 15 b 6 are provided in between these loops 14 b 1 14 b 5 for this tie 1 b the clearance of both ends 11 ba and 11 bb can also be widened when deformed and each contacting portion 15 b 1 15 b 6 can be in pressure contact against intersectional reinforcing bars as shown in fig1 thereby increasing contacting portions against the reinforcing bars this increases the binding strength of the bound portion fig1 is an overall plane view of another configuration example of a tie a tie 1 c has a loop 12 c on the center of a wire rod and wire rods 13 ca and 13 cb on both sides of the loop are formed in line symmetrical across a center line l which runs through the loop 12 c that is the wire rods 13 ca and 13 cb are formed by extending a pair of wire rods which is parallel in a same direction with reference to the loop 12 c as a base end towards a direction away from the center line l curving it to the direction of center line l at the curved portions 141 ca and 141 cb and curving outward direction away from the center line l at the curved portions.
