Vintage Yonezawa Zephyr Convertible Tin Toy with Box

• Friction Motors in Toys - A friction motor, also known as a push and go is a type of motor that uses friction to create motion. It is commonly found in toys, particularly in vehicles such as cars and trains. The motor works by using a spring-loaded mechanism that is activated when the toy is pushed or pulled along a flat surface. The movement of the toy causes the friction between the wheels and the surface to turn the gears inside the motor, which then propels the toy forward.
  
  Friction motors are known for their simplicity and low cost, making them a popular choice for children's toys. They are also easy to use, as they do not require any batteries or electrical power to operate.
  
  However, there are some drawbacks to friction motors. They can wear out over time, especially if the toy is used frequently. They also have limited speed and power, and the motion can be affected by the surface on which the toy is used.
