FIXING STRUCTURE OF ANCHORING PLATE

PROBLEM TO BE SOLVED: To prevent various members constituting a fixing structure of an anchoring plate from being disassembled in mounting. SOLUTION: This fixing structure of the anchoring plate comprises: the two anchoring plates in which approximately U-shaped engaging notches are formed at edges on both sides, respectively, and in which a square hole 2 for being loosely fitted into a handle shaft is opened in a central portion; a pair of mounting columns 7 and 7 which are tubular bodies having a step portion formed at one end of an outer periphery, and in which a female screw is formed in an inner tubular portion; and two pairs of first and second collars 11 and 12 which are fitted into the small-diameter portions of the mounting columns, respectively. These are sequentially fitted into the small-diameter portions of the mounting columns. The second collar for being fitted into the other end of the small-diameter portion is plastically deformed in a radial direction in advance. The second collar is firmly fitted into the small-diameter portion of the mounting column via frictional engagement when being fitted into it. COPYRIGHT: (C)2008,JPO&INPIT
