PURPOSE:To obtain an excellent range of vision without movement of a wiper obstructing the view by fixing a wiper and putting a transparent sheet in reciprocating motion. CONSTITUTION:A transparent sheet 1 is provided in front of a front glass and makes a reciprocating motion by means of a motor 9, clutches 13a.b and reeling cylinders 3a.b. A wiper 7 is fixed in front of said sheet and clears it from waterdrops or the like sticking to its front face through movement of said sheet. Since the wiper is fixed and makes no movement obstructing the view, an excellent range of vision is obtained. |
