It should be noted that the internal structure of the glow engine 31 is well known in the art, so a description thereof will be omitted. Further, the glow engine 31 is provided with a carburetor 41 as shown in FIG. 2(a), and the carburetor 41 is configured to be supplied with fuel from the fuel supply device 33. The carburetor 41 includes an intake hole 41a that takes in air from the outside, and an air valve 41b that opens and closes the air intake hole 41a to adjust the amount of air.

In the above, the fuel mixed with air inside the carburetor 41 becomes a mist-like mixture and passes through the glow engine 3 through the intake hole.
sent into 1. Further, the air valve 41b is operated by the servo motor 38, and a detailed explanation thereof will be given later.

Next, the output shaft 40 of the glow engine 31 is attached to the output shaft 40 of the glow engine 31 as shown in FIG.
), a gear 43 and a flywheel 44 are provided, and the gear 43 is meshed with the gear 1 of the forward/reverse rotation converter. With this, glow engine 3
1 can be reliably transmitted to the gear l of the forward/reverse converter. Further, the flywheel 44 is provided to apply an inertial force to the output shaft 40 to facilitate starting of the glow engine 31.

The starter 3 for starting the glow engine 31
2 is pivotally supported by a gear 52 provided on a rotating shaft 51 and an arm rod 53 rotatably provided on the rotating shaft 51, as shown in FIG. 2(C), and meshes with the gear 52. It is composed of a planetary gear 54, a pulley 55 provided on the rotating shaft 51, a wire 56 wound around the pulley 55, and a handle 57 for pulling the wire 56. and,
The handle 57 constitutes a part of the body 35 of the engine-powered toy 30.

The planetary gear 54 is provided so as to be able to engage and disengage from the gear 1 of the forward/reverse converter. Further, an elastic member 59 is provided between the pulley 55 and the arm rod 53, which applies a rotational force to the pulley 55 to rewind the wire 56, and which rotates while constantly biasing the planetary gear 54 in a direction away from the gear l. has been done. As a result, the normal meshing state between the planetary gear 54 and the gear 1 is released.

A shaft member 61 is rotatably disposed on the upper part of the support member 60 of the operating rod 39 that interlocks with the servo motor 38, and mounting pieces 62, 63 are provided at the tip and approximately the center of the shaft member 61.
is provided. An elastic member 65 is attached to one end of the mounting piece 62, and the elastic member 65
One end is fixed at an appropriate position on the chassis 34 of the engine-powered toy. This allows the shaft member 61 to always return to its original position. Reference numeral 66 indicates a linking member, and one end of the linking member 66 is connected to the air valve 41 of the carburetor 41.
b, the other end is attached to the attachment piece 62 of the shaft member 61, respectively. A support shaft 67 protruding from the bottom surface of the distal end of the mounting piece 63 of the shaft member 61 is loosely fitted into a guide groove 68a of a support member 68 provided on the operating rod 39. As a result, the servo motor 38 causes the clutch means a, a to
The operations of the carburetor 41 and the carburetor 41 can be performed in conjunction with each other.

The fuel supply device 33 includes a bottle-shaped fuel cartridge 70 and a cartridge mounting portion 71 to which the cassette-type fuel tank 70 is mounted. A cap (not shown) is removably provided on the mouth 70a of the cassette fuel tank 70, and
A thread 70b is formed on the outer periphery. Thereby, it is possible to securely attach the cartridge to the cartridge insertion portion 71. Furthermore, locking protrusions 70c, 70c, . . . for preventing slippage are provided on the outer circumferential bottom band of the cartridge 70. Further, the cassette type fuel tank 70 has a body 35.
and the rear bumper 34a.

In the above, when the engine running toy 30 is started, the connector 78 of the power supply section 76 is connected to the connector 74 of the chassis 34.
When the gear 52 is rotated by the pulley 55 and the gear 52 is rotated by the pulley 55, the gear 52 is rotated by the pulley 55.
2 rotates. As a result, the planetary gear 54 rotates against the elastic member 59 toward the gear 1 of the forward/reverse converter and meshes with the gear 1. gear l
is meshed with the gear 43 provided on the output shaft 40 of the glow engine 31, so as a result, the glow engine 31 is started. After starting, when the power source section 76 is removed and the handle 57 is released, the return force of the elastic member 59 causes the pulley 55 to rotate in the reverse direction and the wire 56 to be wound up. Note that starting by the starter 32 is as follows.

It is assumed that this is carried out with the clutch means a and a in the neutral state. That is, the opening 1 of the brake member 7.7
0.10 is transmitted to the operating member 21 via the operating rod 39 by moving the servo motor 38, and is spread by the operating member 21, and the rotational disk 4.4 accommodated in the opening 10, 1O. It shall be free to rotate. by this. The rotational force of the glow engine 31 is 36.36 for the rear wheel.
is not transmitted to the rotary drive shaft 2 to which it is attached, so the running of the engine-powered toy 30 remains stopped.

Next, the servo motor 38 is driven and controlled by radio control to forwardly rotate the rotary cylinder of the operating member 21 loosely fitted to the rotary drive shaft 2 via the operating rod 39. Pieces 23.23 fixed in the 90' crossed position are also rotated in the same way, as shown in FIG. 2fb).

As shown, the brake member 7 of one of the clutch means a, a prevents the rotation of the rotary disk 4 housed in the opening lO, thereby causing the differential gear 6 to rotate. gear 2
6 and the gear 27 provided on the rotary drive shaft 2 are meshed with each other, so that the rear wheel (running wheel) attached to the rotary drive shaft 2
Since 36.36 rotates in the forward direction, the engine-powered toy 30 travels forward. Further, by rotating the servo motor 38 in the opposite direction, the other brake member 71 of the clutch means a, a is tightened by the elastic member 13, and for the same reason as above, the gear 26 provided at the center of the outer surface of the differential gear 6 is tightened. Since the gear 28 provided on the rotary drive shaft 2 is meshed with another gear 29, the rotary drive shaft 2
Since the rear wheels 36 and 36 rotate in the opposite direction, the engine-driven toy 30 travels backwards.The engine-driven toy 30 is stopped by controlling the servo motor 38 to its initial state (neutral). can be done.

As described above, according to the engine running toy 30, after connecting the connector 78 provided on the power supply section 76 to the connector 74 provided on the engine running toy 30 on which the glow engine 31 is mounted, the energization switch 75 is turned on. The glow engine can be easily started by pulling the handle 57 of the starter 32. Further, since the glow engine 31 is equipped with a cassette type fuel tank 70, fuel can be easily replenished and replaced without getting one's hands dirty. Furthermore, the clutch means a, a each include a differential gear 6.6 provided with internal teeth 5.5 that mesh with the planetary gear 3.3.3.3, and an opening l0110 in which the rotating disk 4.4 is housed. The differential gear 6.6 and the rotating disk 4.4 are constructed of a brake member 7.7 having a
It is rotatably attached to the gear shaft 15 of the gear shaft 15, and is meshed with the planetary gear 3.3.3.3 provided on the gear shaft 15, and is provided at the center of the outer surface of one differential gear 6. The gear 8 is meshed with one gear 27 provided on the rotary drive shaft 2, and the gear 8 provided on the outer surface of the other differential gear 6 is meshed with another gear 28 and another gear 29 provided on the rotary drive shaft 2. They are meshed together through the Therefore, by restraining one rotating disk 4 by the brake member 7 of the one clutch means a and releasing the other rotating disk 4 by the brake member 7 of the other clutch means a, the engine or motor can be You can easily rotate the rotary drive shaft 2 without changing the rotation.
Moreover, it can be reliably rotated in the opposite direction.

In addition, since the rotary drive shaft 2 can be rotated in the forward direction by operating the clutch means a, a in the opposite direction, the rotary drive shaft 2 can be rotated in the forward direction without changing the rotation of the output shaft 40 of the glow engine 31. 2 can be reliably rotated in forward and reverse directions, thereby allowing the engine-powered toy 30 to run stably forward or backward.
