Abstract: A boot-band, of which the ear portion is highly rigid, that lowers the prominence of the ear portion. An outer overlap portion and an inner overlap portion are fixed together by inserting hooking claws into holes, with the band-body being curled into the shape of a ring. In a region of the band-body in the circumferential direction is formed an ear portion that has a pair of outwardly prominent leg portions and a bridge portion that connects the leg portions. At the opposite ends of the bridge portion, along a line that is perpendicular to the circumference, are formed rib-like parts that are inwardly bent and between which is formed a dowel portion. The rib-like parts are so arc-shaped that the inward prominence, which protrudes into the ear portion, increases toward the middle of the bridge portion in the clamping direction. The length of the rib-like parts is not long enough for the rib-like parts to reach the curved portions, but is 60% or more of the length of the bridge portion.

Abstract: Provided is a boot band 31 that is capable of preventing the occurrence of buckling in the inner-layer portion of a band body 33. In the boot band 31, by applying a diameter-reducing tightening force on the band body 33 when an engagement pawl 41 of the inner-layer portion 35 of the band body 33 has entered a top-end engagement hole 42 of the outer-layer portion 34 of the band body 33, the top-end engagement hole 42 rides over the engagement pawl 41. Buckling is prevented by providing, at the area of the top-end engagement hole 42 opposite where the engagement pawl 41 enters therein, a guide means 51 that faces the engagement pawl 41.

Abstract: There are provided a plurality of pressing members (2) provided in the radial state with the tips oriented to a central axis (0) of a substrate (1) capable of moving back and forth the tips to and from the central axis (0) on a prespecified plane; a rotational body (3) rotatably provided on the substrate (1) around the central axis (0); and driven units (25, 32) for moving forward tips of the pressing members (2) toward the central axis (0) in association with rotation of the rotational body (3) to apply force to the ring with the tips of the pressing members (2) from outside of the ring. In this state, force is applied to the ring with the tips moving forward from outside of the ring. Furthermore, hooking units (16, 26) for hooking the ring on the tips are provided. In addition, a holding unit (7) is provided for positioning and holding a mounting body against the central axis (O).
