ANCHORING PLATE FIXING STRUCTURE

PROBLEM TO BE SOLVED: To provide anchoring plates which can be certainly fixed to a door body without looseness. SOLUTION: An anchoring plate fixing structure has: an anchoring plate forming almost U-shaped linking notches respectively formed on both the side edges and having a square hole loosely fitting to a handle axis at a central portion; a pair of installing poles forming a female screw in an inner cylindrical portion by a cylinder forming a step part on an end of an outer periphery; and a collar fitted to a small diameter portion of the installing pole. A dimension adding a length of the collar to a thickness of the anchoring plate is set greater than the length the small diameter portion of the installing pole, and the anchoring plate is firmly fixed to the inside of a door through the installing pole by screwing attaching bolts penetrating through a seat plate sandwiching the door into female screw holes of the installing poles in a state where a notched portion of the anchoring plate is sandwiched between an end of the collar fitted to the installing poles and the step part of the installing pole.
