<P>PROBLEM TO BE SOLVED: To provide a fixing device including a separation preventing member capable of preventing a bolt from being lost by preventing separation of a fixing object and the bolt even when the bolt is detached from an object and the fixing object is detached from the object. <P>SOLUTION: When a male threaded portion 173 of an attaching bolt 145 is successively inserted into an attaching hole 167 of a pressurizing and fixing member 143, a conical type coil spring 149, and an insertion hole 160 of an attaching member 142, and threadedly engaged into a screw hole 172 of a thread engagement receiving member 144, a pressurizing pawl portion 168 of the pressurizing and fixing member 143 pressurizes the upper side part of the outer frame 9 of a game machine from below, and thus an outer frame 9 is fixed to an upper frame 4 of bank of game machines. The conical type coil spring 149 is formed in a coil shape by gradually reducing the coil winding diameter from an upper end to a lower end, and the coil winding diameter at the lower part is set to be almost same as a screw diameter of the male threaded portion 173. <P>COPYRIGHT: (C)2013,JPO&INPIT |
