When the rubber button is pressed, the switch is turned on by contact of the pair of contacts. . At this time, the rubber button makes a pair of contacts contact or releases the contact.
Therefore, when the pressing force of the rubber button exceeds a certain value, the pair of contacts come into contact, and when the pressing force of the rubber button falls below a certain value, the pair of contacts opens. As described above, the conventional push button switch simply switches on or off by pressing the rubber button or releasing the pressing.

Conversely, when the pressing force is reduced, the switch base SWa is reduced. The contact area between the switch piece and the switch piece SWb is reduced, so that the contact resistance is increased. Therefore, in the initial state where no pressing force is applied to the switch piece SWb, the contact resistance between the switch base SWa and the switch piece SWb is almost infinite, and the contact resistance becomes linear or non-linear as the pressing force increases.

Since the contact resistance changes in accordance with the pressing force as described above, the rotation speed of the motor M can be easily changed in accordance with the change in the contact resistance, and the rotation speed of the rotating body can be easily controlled. .

When the switch piece SWb is pressed against the switch base SWa, a contact resistance corresponding to the pressing force is generated between the switch piece SWb and the switch base SWa. That is, when the switch piece SWb is pressed against the switch base SWa, the contact area between the switch base SWa and the switch piece SWb increases in accordance with the pressing force, so that the contact resistance decreases. Conversely, when the pressing force is reduced, the switch base SWa is reduced. The contact area between the switch piece and the switch piece SWb is reduced, so that the contact resistance is increased. Therefore, in the initial state where no pressing force is applied to the switch piece SWb, the contact resistance between the switch base SWa and the switch piece SWb is almost infinite, and the contact resistance becomes linear or non-linear as the pressing force increases.

The striking plate 21 is provided at a position where it is struck by the ring members 17a and 17b projecting outward by centrifugal force caused by the rotation of the rotating base 13. That is, when the rotating base 13 is stopped, the striking plate 21 is
The tip of the tapping plate 21 is attached in a state warped upward so as not to come into contact with b. When the rotation base 13 rotates, the tapping plate 21 is hit by the ring members 17a and 17b protruding outside the opening 19a due to the centrifugal force. Here, in the above example, the rotating shaft 11

As described above, the contact resistance changes in accordance with the pressing force of the push button switch SW. Therefore, the rotational speed of the motor M can be easily changed by adjusting the pressing force of the push button switch SW. For example, when the push button switch SW is pressed strongly, the motor M rotates at a high speed,
When the pressing force of the push button switch SW is reduced, the motor M rotates at a low speed.

Since the propeller 5 is loosely fitted on the rotating shaft 25 rotated by the motor M, the propeller 5 rotates following the rotation of the motor M. Therefore, the rotational speed of the propeller 5 can be easily controlled by adjusting the pressing force of the push button switch SW. Here, since the propeller 5 is loosely fitted so that it can idle, even if the infant touches the rotating propeller 5 by mistake, only the propeller 5 idles, so that the safe aircraft toy 1 can be realized. it can.

The rotation of the motor M activates the sound generating mechanism to generate a sound such as an engine sound. This sound generating mechanism has a rotating base 13 which is mounted on a rotating shaft 11 of a motor M.
1 have shaft portions 15a and 15b parallel to
Ring members 17a and 17b having inner diameters larger than the diameters of the shaft portions 15a and 15b are inserted into a and 15b. A striking plate 21 is provided at a position struck by the ring members 17a and 17b.
When the ring members 17a, 17b protrude outward due to the centrifugal force caused by the rotation of the motor M, the striking plate 21 is hit by the protruding ring members 17a, 17b, so that a loud tapping sound is generated as the rotational speed of the motor M increases. Can be done. At this time, the cap 19 functions as a resonance box,
The striking plate 21 is continuously struck by the ring members 17a and 17b, so that a large volume with a volume such as an engine sound can be generated. Also,
There is a case where the user wants to enjoy the change of the volume of the engine sound at that time by causing the airplane toy 1 to rapidly rise or fall during play. In this case, the strength of the tapping sound can be reliably changed by increasing or decreasing the pressing force of the push button switch SW in accordance with the sudden rise or fall of the toy 1 with the airplane toy. Can be easily reproduced, so that interest can be enhanced.
