Abstract
An angle-adjusting device for the wind-resisting plates of the resisting wheel of a stationary bike includes an adjusting button for actuating a pushing unit on the shaft of a resisting wheel to rotate. A coupled rotary sleeve fitted in the pushing unit and restricted to shift axially has its inner wall fixed with an offset-angled projecting member. A main gear unit fitted on the shaft by a bearing has a sleeve having one end inserted in the coupled rotary sleeve and bored with an oblique recess for the offset-angled projecting member to engage with and a main bevel gear having its toothed side facing the resisting wheel. The wind-resisting plates have their shafts respectively provided with an auxiliary bevel gear engaged with the main bevel gear. The angles of the wind-resisting plates can be adjusted by pulling the adjusting button.
