<p><P>PROBLEM TO BE SOLVED: To provide an operation handle for game machines, which is capable of surely preventing an act of inserting foreign matter for fixing a turning ring part to a desired turning position, in a simple constitution. <P>SOLUTION: This operation handle 1 for game machines has a body base part (a fixed base part) 2 fixed to the front panel of a game machine, and the rotational ring part 3 operated turning around a central axis C of the body base part 2 for adjusting the shooting strength of game balls. An inclined clearance 5A inclined relative to the direction of the central axis C is provided around the whole circumference between the body base part 2 and the rotational ring part 3. The turning ring part 3 has an insertion prevention wall 6A for preventing the act of inserting the foreign matter in an opening part 51 of the inclined clearance 5A, around the outward whole circumference along the inclination direction of the opening part 51 of the inclined clearance 5A. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
