The present invention relates to a device for cleaning at least one optical surface of a vehicle, including at least one rod which extends mainly along a longitudinal elongation axis. The rod including an element for spraying a cleaning fluid and a wiper blade configured to wipe the optical surface. The device further including at least one actuation means driven to move the rod in a first longitudinal direction of movement parallel to the longitudinal elongation axis, and in a second longitudinal direction of movement opposite to the first longitudinal direction of movement. The device additionally includes at least one means for limiting and/or compensating for at least one return force exerted on the rod.

Provided is a compact and high-strength cab capable of securing an excellent field of view for work. The cab includes a guard protecting a cab body, and a wiper having a blade to wipe a front window member and a blade actuator for actuating the blade. The guard includes a pair of side pillars and an actuator housing beam interconnecting the side pillars and housing the blade actuator. The actuator housing beam includes a hollow beam body formed with a body opening and a front-rear partition plate partitioning the inside of the beam body into front and rear sections. The body opening allows the blade actuator to be assembled to the front-rear partition plate therethrough.

A reciprocating wiper system according to the present invention may include a guide rail; a carrier unit coupled to be slidable in the guide rail and installed to reciprocate in a longitudinal direction of the guide rail; a cam member installed to be rotatable on the carrier unit; a wiper arm coupled to the cam member to move integrally with the cam member and to which a blade is coupled; a first pressing member for aligning the wiper arm in a direction perpendicular to the guide rail by rotating the cam member while the carrier unit is moving in a forward direction along the guide rail; and a second pressing member for aligning the wiper arm in a direction parallel to the guide rail by rotating the cam member while the carrier unit is moving in a reverse direction along the guide rail.

A rocker-type assembly device for a wiper includes a wiper fastening base (1), a connection base (2), and a control member (3). The wiper fastening base (1) is fixed to a wiper body (900) and has a shaft (11) and a buckling portion (12). The connection base (2) is combined with the wiper fastening base (1) and has a shaft groove (21) receiving the shaft (11). The connection base (2) swings in a rocker-like manner about the shaft (11) as a pivot. The swing arm (800) is assembled to the connection base (2). The control member (3) includes a buckling body (31) and swings together with the connection base (2) to drive the buckling body (31) to be engaged with the buckling portion (12) or disengaged from the buckling portion (12).

A windshield wiper system (WWS) is provided and includes a brushless direct current (BLDC) motor with a motor output shaft gear, a gear train and an internally cut sector gear. The gear train includes a first gear, which has a first diameter and engages with the motor output shaft gear, and a second gear, which has a second diameter that is shorter than the first diameter and rotates with the first gear. The internally cut sector gear is coupled with an output shaft and formed to define an internal geared groove that engages with the second gear.
