Abstract
A linear-motion wiper structure comprising a multistage hydraulic cylinder arm which can be driven by a transmission mechanism having both vertical and horizontal displacement function whereby a blade, which is driven by the arm, can wipe on the windshield in a linear reciprocating motion so as to completely clear the drops of rain on the windshield, and this may provide a clear vision for users who drive in the rain.
