Then, by engaging the male key portion 120 and the female key portion 121, the band-shaped body 118 is formed in an annular shape, and the member to be tightened is held in a tightened state on the mating member.

By the way, when the boot band is attached, a load is applied by the fastening force at the time of attachment, and the reaction force acts as a tensile load. This tensile load may cause the female key portion to widen in some cases and reduce the strength of the female key portion. In view of this, a technique for improving the strength of the male-female engagement structure has been proposed (Patent Document 1). In Patent Document 1, as shown in FIG. 9, a male key portion 120 having protrusions 122 projecting on both sides in the width direction is provided at the distal end portion of one end portion 119a of the strip 118, and the distal end portion of the other end portion 119b. A female key 121 having an engaging groove 123 that fits into the protrusion is provided. The male key portion 120 includes a main body portion 124 whose width dimension becomes narrower toward the end portion, and a trapezoidal protrusion 122 provided continuously from a side portion of the main body portion 124. Thereby, there exists a surface orthogonal to the direction of the tensile load with respect to the tensile load acting on the male / female engaging structure, and this surface restricts the widening of the female key portion 121.
