Abstract
A wiper apparatus suitable to wipe the window pane of laterally elongated type, which is provide with a reversible wiper motor 2; a reciprocally rotating output shaft 2a; a circular shaped rotary housing 3 fixed to the output shaft; a stationary gear 4 disposed coaxially around about the output; an idler gear 5 meshed with the stationary gear and supported rotatably on the rotary housing; an output gear 6 meshed with the idler gear and supported rotatably on the rotary housing; and a pivot shaft 20 fixed to the output gear and connected with a wiper member 7, 8; the gears 4, 5 and 6 are housed in the rotary housing 3.
Claims5
A wiper apparatus for wiping a window pane of a vehicle comprising:
- a wiper motor of a reversible type fixed on a body of said vehicle;
- a output shaft rotated reciprocally by said wiper motor in clockwise and anti-clockwise directions alternatively;
- a rotary housing fixed to said output shaft for rotating reciprocally together with the output shaft;
- a stationary gear disposed coaxially around about said output shaft and fixed on said vehicle body;
- an idler gear supported rotatably on said rotary housing and meshed with said stationary gear for reciprocally rotating on said rotary housing according to the reciprocating rotation of said rotary housing;
- an output gear supported rotatably on said rotary housing and driven rotationally by engaging with said idler gear;
- a pivot shaft supported rotatably on said rotary housing and fixed to said output gear;
- and
- wiper members connected to said pivot shaft;
- wherein said rotary housing is formed in a circular shape, fixed coaxially to said output shaft and has a radius sufficient to house said stationary gear, said idler gear and said output gear;
- and
- wherein said rotary housing is contained in a cavity formed on said vehicle body.
