When 1 is engaged with the high cam protrusion 52a of the first cam 52, the slide lever 80 slides in the rightward direction shown in FIG. 8, and the tip end portion 85 of the swing lever 84 is slid as shown in FIG. 8C. The tip end 87 of the swing lever 84 is in the position shown by the chain line C ′ in the opening 89 shown in FIG. 9, and the swing lever 84 is moved to this position by the pulling spring 88. It is stably held, and the rightward movement of the slide lever 80 is locked, so that the motor 8 is continuously driven. This is the engine idling state, and the drive force is transmitted by the motor pinion 9-gear 33-pinion 34-pinion 37-.
The gears 38 are rotated in this order, and the first cam 52 and the second cam 53 are rotated via the worm gear 41 and the worm wheel 51. Further, the contact piece 42 coaxial with the gear 38 is rotated to generate an engine sound, the propeller 5 is rotated via the pinion 43, and the eccentric cam 69 moves the cowling 4. At this time, the upper end portion 49 of the rotating plate 47 is engaged with the engaging wall surface 97c in the recess 97 of the slide plate 93 as shown in FIG.
Rotates clockwise about the gear shaft 30 as a fulcrum, the pinion 48 meshes with the pinion 35 and rotates idly, and no driving force is transmitted to the drive wheels 67, 67 side.

Next, when the operation knob 3 is moved to the "traveling" position, the upper end portion 49 of the rotating plate 47 slides from the engagement wall surface 97c shown in FIG. 9 to the engagement slope 97a and engages with the engagement wall surface 97b. As a result, the rotating plate 47 rotates in the counterclockwise direction shown in FIG. 2 and the pinion 48 meshes with the gear 39 and the gear 54. The gear ratio of the pinion 48 and the gear 39 is designed to rotate the gear shaft 40 at a higher speed than the gear ratio of the pinion 37 and the gear 38.
Is separated from the gear 38 and idles. Thus, the main body 1 is driven by the drive mechanism that rotates at a higher speed than during idling.
Drives to drive.

Next, when the main body 1 is separated from the floor surface, the leg portion 71 pivotally supported on the main body 1 rotates in the counterclockwise direction shown in the second figure with the support shafts 72, 72 as fulcrums. The protrusion 73 of the leg portion 71 rotated counterclockwise is separated from the cam protrusion of the second cam 53, and the protrusion 74 protruding from the protruding piece 71a engages with the lower end of the rotation lever 29 to move the rotation lever 29. It is rotated clockwise in the second illustration. By rotating the rotation lever 29 clockwise, the pinion 37 is separated from the gear 38, and the pinion 36 designed to rotate the gear shaft 40 at the highest speed meshes with the gear 38. Then, the pinion 48 is separated from the gear 39 that rotates at a higher speed and idles, so that the driving force is not transmitted to the drive wheels 67, 67. On the other hand, in the aircraft body 1 that has left the floor surface, the propeller 5 rotates at high speed, and a high-pitched engine sound can be generated by the contact piece 42 rotating at high speed. And
When the drive mechanism is stopped, the operation knob 3 may be pulled to the rear of the main body 1, and when the slide plate 93 shown in FIG. 6 is retracted, the engaging stepped portion 94 is attached to the upper end portion 87 of the swing lever 84. It engages and pulls back the upper end 87 upward from B'shown in FIG. At this time, the slide lever 80 moves in the leftward direction shown in FIG. 2, the conductive contact piece 11 and the terminal 10 of the motor 8 are separated, and the motor 8 stops. Then, the swing lever 8
The upper end portion 87 of the No. 4 is pulled by a pulling spring 88 to A'in FIG.
Therefore, the operation knob 3 is again stopped at the "start" position.
