To provide an operation member for changing a steering angle of a steering wheel of a vehicle corresponding to an operation of the operation part; and a steering wheel operation device for a vehicle provided with the operation member in which the operation part does not exist at an upper side position between a left operation part and a right operation part at the time of linear advancement of the vehicle; and the operation device capable of smoothly operating the operation member at the time of linear backward advancement of the vehicle.

In the steering wheel operation device 10 of this vehicle, when the vehicle starts to rearwardly advance (step 315), a control stick 23 is rotated while maintaining steering angles θs of steering wheels Tfl, Tfr to a reference angle '0' to be capable of arranging one of right and left operation parts 23L, 23R at an upper side position (step 325). When the case where the vehicle is rearwardly advanced is completed (step 340), the control stick 23 is rotated and returned while maintaining the steering angles θs of the steering wheels Tfl, Tfr to the reference angle to be capable of returning the positions of the right and left operation parts 23L, 23R to a neutral position such that the operation part does not exist at the upper side position (step 345).
