PURPOSE:To obtain a feeling of smooth centering without a sense of spring by providing a centering mechanism on the side of an operation rod and adopting the resistance of a roll rotated to a V-shaped cam at the time of centering of the operation rod. CONSTITUTION:An orthogonal shaft perpendicular to a plane, which includes the center line of an operation rod 10 in the end part of the operation rod 10, is provided on this plane and is freely inclinably attached by a lateral hole of a turning shaft 4 on the plane, and the turning shaft 4 is freely turnably attached to a frame body 1. One or more slide shafts 6 which have axes on opposite side of a tetragon having the turning shaft 4 as one side on a plane including the turning shaft 4 are freely slidably attached to the turning frame body, which is stuck to the turning shaft 4, in the axial directions of slide shafts, and end parts of slide shafts 6 are connected to one end of the operation rod 10. V-shaped members inclined in a V shape are stuck to slide shafts 6 in the sliding directions of slide shafts 6. Thus, the operation rod 10 is operated in crosswise directions, and the centering force always smoothly acts by energizing means of V-shaped members. |
