<p><P>PROBLEM TO BE SOLVED: To provide a snappy holding structure having a snappy end portion which is easily attached using one attachment plate, having reliable clamping force thereby preventing the snappy end portion from being loosened, and preventing breakage of the snappy end portion, without requiring delicate adjustment. <P>SOLUTION: Inner faces 31a and 32a of each clamp piece of the attachment plate 76 are formed into a flat or curved face tilted to the same side of a bolt shaft direction by less than 90 degrees, with reference to a virtual face 35 perpendicular to the bolt shaft. According to a shape of the inner face of each clamp piece, portions facing each clamp piece of the snappy attachment face 30 are each formed into the flat or curved face, which is parallel to the inner face of each clamp piece. Thereby, a force P along the shaft direction obtained by fastening the bolt 77 acts on the inner face of each clamp piece as force P' which is increased by wedge effect, and the snappy end portion is firmly clamped between the snappy attachment face 30 and the attachment plate 76 by the increased clamping force. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
