速機操作装置。 By supplying and discharging pressure fluid to a pair of pressure chambers formed on both sides of the piston and stroking the piston rod in the cylinder, a damping force is applied to the piston rod when driving the gear shift fork in the gear engagement direction or neutral direction. A transmission operating device configured to do so, further comprising a relief valve that releases damper pressure when the damper force exceeds a predetermined value.
