公報参照）。Conventional automatic deceleration devices for traveling aircraft include a working device that can be raised and lowered, a belt-type continuous transmission device for traveling that changes speed using a tension pulley, and a speed change device that is connected to the tension pulley via a mechanical linkage mechanism. In addition, a locking device for holding the gear shift operation position is provided on the manual operating tool, and a balance spring for reducing the operating force toward the deceleration side is stretched between the manual operating tool and the fixed part. An interlocking member for automatic deceleration is provided in the middle of the mechanical interlocking mechanism to decelerate the non-permanent transmission device from a high speed state to a low speed state in conjunction with the lifting of the working device, and the automatic deceleration allows operation of the manual operating tool. A flexible portion for dissipating force transmission is formed between the interlocking member and the human operating tool (for example, see Japanese Patent Laid-Open No. 126904/1983).

A plurality of locking grooves (19a) are formed in the lever guide (19) along the speed change operation direction. Main gearshift/<-(
10) This locking groove (19) is attached to the shaft by the force of a compression spring (10b).
A pin (10a) biased toward the a) side is provided, and a push button (10c) for unlocking is provided at the upper end of the lever (10).
), so that the shift operation position of the main shift lever (10) can be held and released. When the machine body rotation is completed and the planting device (D) is lowered, the speed is automatically increased by the biasing force of the spring (15) provided on the split pulley (11).

The biasing force of the balance spring (23) is only stopped by the locking action of the pin (10a), and if the lock is released due to vibration of the aircraft or incorrect operation of the push button (10c), the main shift lever (10 ) will bounce back to the deceleration side with great force. To prevent this, the pin (10a) during automatic deceleration
The lock piece (24) that prevents the main gear shift lever (1
0) The shaft is pivotably supported around the horizontal axis (P3), and the outer wire of the release wire <25a)
The end of the main shift lever (10) and the interlocking member (20)
The inner wire (25b) is attached to the upper end of the long hole (20b), and the end of the inner wire (25b) is connected between the lock piece (24) and the lower end of the operating rod (21). With this configuration, when the interlocking member (20) rotates due to automatic deceleration as the planting device (D) rises, the distance between the lower end of the outer wire (25a) and the operating rod (21) increases, and the distance between the lower end of the outer wire (25a) and the operating rod (21) increases. ) through the lock piece (24) and the pin (10a
