<P>PROBLEM TO BE SOLVED: To provide an escalator jig by which a tightening member used in a truss of the escalator can be optimally pulled out. <P>SOLUTION: The escalator jig 10 which is used for tightening a tightening target portion in the truss 58 of the escalator 7 and pulling out the tightening member 47 having a head 472 and a body 474 has: an inserting part 110 including a tapered portion which can be inserted between the tightening target portion and the head 472; and an extending part 120 which extends from the inserting part 110. The inserting part 110 is inclined with a base end 114 of the inserting portion 110 as a supporting point when an external force is applied to the extending portion 120 so that a tip 112 of the inserting part 110 pushes the head 472 up in the pull-out direction. <P>COPYRIGHT: (C)2012,JPO&INPIT |
