に制動がかかり、機体はその方向に急旋回する。In the diagonal configuration, when the steering transmission gear 2 is engaged with the dog portion 1a of the transmission input gear 1 (the left side of FIG. 1 shows the engaged state), the transmission input gear 1 is engaged. ]
The power is transmitted to the traveling section via the steering transmission gear 2 and the transmission gear 5, and the aircraft moves straight, but by operating the shifter 4, the steering transmission gear 2 is tilted left or right, or one of the steering transmission gears 2 is pushed by the restoring projectile 1'8. It detaches from the dog portion 1a of the transmission input gear 1 against the pressure (
If the steering clutch is disengaged) and the engaging pawl 7 of the steering transmission gear 2 is engaged with the engaging pawl 8 of the engaging body 9, the transmission gear 5
The brakes are applied and the aircraft makes a sharp turn in that direction.

ることができる。In short, the present invention provides a steering clutch in which the steering transmission gear configured in the steering clutch is disengaged from the transmission input gear on the negative side and engaged with the engaging body on the other side via the engaging pawl to be locked. In the locking device, the engaging body is rotatably supported within a certain range in the forward and reverse rotation directions of the steering transmission gear via the opposing shock absorber, so it is rotatable within a certain range. Even if the engaging body is supported by the steering clutch, the engaging body rotates integrally with the steering transmission gear that engages when the steering clutch is operated, before being regulated within a certain range.
The rotational force is buffered by the buffer bullet facing the rotational direction side of the steering transmission gear, and the impact in the rotational direction of the engaging body can be absorbed.
しかも、係合体が正転方向に規制された際、係合体に作
用する操向伝動歯車の逆転方向の衝撃を、正転方向に対
向する逆転方向の緩衝弾機で吸収することができる。Moreover, when the engaging body is restricted in the normal rotation direction, the impact of the steering transmission gear in the reverse direction acting on the engaging body can be absorbed by the shock absorber in the reverse direction opposite to the normal rotation direction.
したがって、操向伝動歯車を係合体に噛合させる際の係

せてできる。Therefore, in addition to absorbing the impact of the engaging body in the forward and reverse directions when the steering transmission gear is engaged with the engaging body, the impact on the driver when operating the steering clutch is greatly reduced. At the same time, it is possible to prevent damage to the interlocking claws.
