成されている操向操作装置。 The steering operating tool 1 is capable of reciprocating in the order of a neutral position, a clutch disengaged position, and a brake applied position, and is biased to return to the neutral position, the steering clutch 10 is engaged, and the steering brake 11 is released. The steering clutch is biased to return to the clutch engaged position, and operates to disengage the steering clutch 10 during initial movement from the clutch engaged position, and operates the steering brake 11 to a braking state during subsequent movement. Operating tool 8
and a steering operating device in which the steering operating tool 1 moves from the neutral position to the clutch disengaged position or beyond a position on the near side thereof to the brake application position. A detection means 5 is provided for detecting that the steering operation tool 1 is in a steering operation state, and a biasing means 3 for biasing the steering operation tool 1 toward the brake operation position is activated by the detection means 5. The biasing means 3 is provided to operate when it is detected that the steering brake 11 is in the operating state, and the biasing means 3 biases the steering brake 11 with a biasing force that is insufficient to operate the steering brake 11 into the operating state. A steering operating device configured to.
