（図１及び図３）。BEST MODE FOR CARRYING OUT THE INVENTION An example of an embodiment of the present invention will be described with reference to FIGS. The hose band is a metal strip 10 having a restoring force as shown in FIG.
The hose band 1 having a shape as shown in FIG. 1 is integrally formed by bending the hose into an annular shape. An opening 11 is formed on one end side of the metal strip 10 and a width strip 12 that can be inserted into the opening 11 is formed on the other end side (FIG. 2). The metal strip 10 is bent into an arc shape so as to be inserted and arranged in the ring 11 to form the annular portion 2.
On both end sides of the metal strip 10, an expanded portion 3 in which an opening 11 is slightly bent to the anti-annular portion 2 side by 90 degrees, and similarly, an expanded portion in which a narrow strip 12 is bent to the anti-annular portion 2 side. 4 are formed (FIGS. 1 and 3).

And the width strip 12 formed on the other end side of the metal strip 10
Has a square portion 13 on the tip side, and is gradually widened in the direction from the square portion 13 to the annular portion forming side. Further, the rectangular portion 13 is bent to form the expanded portion 4. The shapes of the opening 11 and the narrow strip 12 are configured as described above because the width of the narrow strip 12 is inserted and arranged in the opening 11 while ensuring the strength of the expanded portions 3 and 4 of the hose band. This is because when the band 10 is bent into an arcuate state to form the annular portion 2, the shape is made easy to insert.

ている。The annular portion 2 is formed with three grooves 14, 15 and 16 in a protruding shape on the surface side of the annular portion 2 along the circumferential direction thereof. The outer grooves 14 and 16 on both sides are formed from the vicinity of the opening 11 of the metal strip 10 to the vicinity of the narrow strip 12 (FIG. 2) to ensure the overall strength of the metal strip 10 and reduce the plate thickness as much as possible. I have to. In addition, the inner groove 15 located in the center is the outer groove 1 in the circumferential direction of the annular portion 2.
The length of the groove is shorter than the length of the grooves 4 and 16 (the length of the inner groove 15 is approximately ½ of the length of the outer grooves 14 and 16). The inner groove 15 and the outer grooves 14 and 16 are different from each other only in length, and are formed to have the same width and height (depth).

The cross section AA at the center position of the annular portion 2 has a shape in which there are three convex portions as shown in FIG. 5, and the cross section at the end side position is the central convex portion (inner groove 15) with respect to FIG. ) Is omitted. Therefore, the strength of the annular portion 2 becomes stronger in the central portion than in the end portion side, and the elasticity of each portion of the annular portion 2 can be changed. As a result, when the expanding portions 3 and 4 are brought close to each other and a force is applied in a direction to push the annular portion 2 open, the end portion side is weaker than the strength of the central portion of the annular portion 2, so that the annular portion 2 is bent. By equalizing the stress on the entire circumference, it is possible to maintain the roundness of the bent state.

For example, in the case of four, the inner two are formed short and the two outer are formed long, and in the case of five, the central groove is shortest, the outer two are next shorted, and the outermost two grooves are formed. It may be formed long.

Can be strengthened, and when a force is applied in the direction to push the annular part open, the bending stress in the annular part can be equalized over the entire circumference, and a perfect circle in a bent state regardless of the degree of opening and expansion of the annular part. You can keep your sex. Further, since the strength of the central portion of the annular portion is strengthened by forming the plurality of grooves, it is possible to reduce the plate thickness of the metal strip forming the hose band while ensuring the overall strength.
