PURPOSE:To make it possible to generate vibration by use of a motor and a simple mechanical arrangement alone by providing a spring secured at one end to the other end of a blade and by providing a balance weight slidably positioned at the other end of the spring. CONSTITUTION:When an automobile in a screen on a television rests, a motor 101, that is, a blade 3 will not rotates, and accordingly, a mode vehicle in front of the TV screen is held to be rested. When the automobile is started to be moved, the blade 3 starts its rotation about a rotary shaft 10 in association with the movement of the automobile, and the model vehicle in front of the screen is slightly oscillated due to unbalance between a fixing weight 8 and a balance weight 103 on the blade 3. Manipulation is made so as to move the automobile in the screen at a higher speed, the frequency of unbalance between the fixing weight 8 and the balance weight 103 increasing, and as a result, a high frequency oscillation occurs on the vehicle mode in front of the screen. In other words, in the case of a low speed, low frequency oscillation having a large oscillating amplitude occurs at a low rotational speed while in the case of a high speed, a high frequency oscillation having a small amplitude occurs at a high rotational speed. |
