DEFINITION

Classification: 476/21

Intermediate idler between input and output gears:

(under subclass 18) Subject matter wherein said rotary motion transmitting parts include a first element rotatable by said input body, a second element rotatably connected to said output body and a third element rotatable about its own axis; said third element having surface portions sequentially contacting said first and second elements to transmit rotary motion from said first element to said second element via said third element by surface friction of rolling contact between said third element and said first and second elements.
