Skateboard |
摘要 |
The skateboard includes only one forward roller and one rearward roller both of sufficient width to provide stability. Each roller is rotatably supported by a combined fork and fender member which in turn is supported to the underside of the board in a manner to permit swivelling about a journal axis formed at an angle to the longitudinal axis of the board. A cantilevered leaf spring in the main frame portion cooperates with a pinion in the journal for the swivel axis to return the roller to a neutral position.
