- the reaction force applied to the left and right grips 10L and 10R when the pinion gear 4 rotates relative to the guide member 2 is such that the steering member 1 and the guide member 2 are moved around the input shaft 3 as a whole. It is smaller than the reaction force applied to the left and right grips 10L, 10R when rotating. For this reason, since the operation in the second movement direction M2 is finally performed before the first movement direction M1, the left and right grips 10L, 10R of the left and right grips 10L, 10R are at the small steering angle for rotating the input shaft 3 small.

I can. For this reason, the driver operates the grips 10L and 10R small when operating the small steering angle, and operates the grips 10L and 10R large when performing the large steering angle operation. Accordingly, since the driver's operation is an operation in accordance with the rudder angle, it is possible to reduce the burden when performing the small rudder angle operation and to match the operation amount with respect to the rudder angle to the driver's sense.
