る高速後進牽制装置。 A steering handle 7 is equipped so as to be freely redirectable in the longitudinal direction of the aircraft, and on the side of the transmission case 3 there are both transmission shafts 12, 11 for high speed and low speed of the main transmission.
In a management machine configured by disposing and sub-shifting shaft 13, a frame 17 that can rotate around a horizontal shaft 9.
A change lever 8 is attached to the change lever 8 so as to be freely changeable in the longitudinal direction, and a restraining plate 8a is fixed to the change lever 8.
, 11.
The frame body 17 is provided with a restraining rod 21 that is fitted into the frame body 17 so as to be movable in the vertical direction, and when the change lever 8 is moved forward, the restraining plate 8a is also integrated. The change lever 8 is rotated to be located above the upper end of the check rod 21.
When the check plate 8a is moved downward and engaged with the change arm 18a, the check plate 8a is moved to the check rod 21 due to this movement.
When the check lever 8 is operated and the change arm 18a engages with the high-speed transmission shaft 12, the protruding lower end of the check rod 21 A high-speed reverse check device in a management machine, characterized in that the auxiliary transmission shaft 13 is located within a shift region in which the sub-shift shaft 13 is shifted to a high-speed side.
