<p><P>PROBLEM TO BE SOLVED: To provide a bearing component hoisting tool easily being attached and detached to/from a large type bearing component that holds a plurality of rollers by a pin-type holder. <P>SOLUTION: As a connecting means for connecting a pair of hoisting members 12, 13 which have insertion pins 12a and 13a inserted into holes 1a, 2a for hoisting side plates 1, 2 of a pin-type holder, a rod 16 whose one end is fixed to a first hoisting member 11 is inserted through a coil spring 17 and a second hoisting member 12 from the other end, a tightening nut 18 mounted on the other end of the rod 16 so as to be threaded and the large diameter portion 16a of the rod sandwich the coil spring 17 and the second hoisting member 13 therebetween, and maintain a prescribed distance between the insertion pins 12a, 13a of the hoisting members 12, 13, wherein the distance between the insertion pin 12a, 13a can be shortened only by compressing the coil spring 17, thus enabling the hoisting tool 11 to be attached and detached more easily to/from a bearing component A than a conventional method. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
