<p>PROBLEM TO BE SOLVED: To adjust delicate moving direction and distance in operation of an operation lever with the palm of the hand by installing a suction disk for sucking the palm of a user in contact with a game machine operating unit at the top end of a pillar-shaped part. SOLUTION: A suction disk 13 formed at the top end of a pillar-shaped part 11 of an operation lever cover 10 is made of an elastic material such as a soft synthetic resin or synthetic rubber. The suction disk 13 is formed in a cup shape, and the cup-shaped part acts as the suction disk for sucking the palm of a user in contact with it. The suction disk 13 has the cup-shaped part whose diameter is preferably larger than that of the pillar-shaped part 11, more preferably it is two times or more, and the thickness of the cup-shaped part is made thinner toward the periphery so as to be easily sucked to the cavity of the palm. More preferably, a cup-shaped part has a flat part connecting to the pillar-shaped part, and is widened upward from the position corresponding to the outer circumferential part of the pillar-shaped part toward the outside.</p> |
