A wiper device includes a pivot shaft, a pivot holder, a water receiving cap and a washer. The pivot holder includes a pivot support portion and a mounting leg. The pivot support portion pivotally supports the pivot shaft. The water receiving cap includes a boss portion and an umbrella portion. The boss portion is fitted onto the pivot support portion. The washer is fixed to a circumference of the pivot shaft at a portion projecting from a distal end of the pivot support portion. At least part of the boss portion overlaps the washer in an axial direction. The umbrella portion includes a projection that projects in the axial direction. The projection opposes the mounting leg in a circumferential direction without engaging the mounting leg in the axial direction.

An automobile vehicle wiper arm system includes a wiper arm base rotatably connected to a fixed structural member. A wiper arm extension is slidably disposed to the wiper arm base during wiper arm base travel about an arc of travel. A motion link is rotatably connected to the wiper arm extension and is rotatably connected to the fixed structural member. The motion link induces the wiper arm extension to outwardly displace and inwardly displace opposite to the outward displacement during wiper arm base rotation about the arc of travel. A wiper blade is connected to the wiper arm extension and traverses an oval-shaped travel arc along a vehicle windshield by the slidable displacement of the wiper arm extension during wiper arm base rotation. A linkage group connects the wiper arm extension to a wiper motor with rotation of the wiper arm base induced by operation of the wiper motor.

The present invention consists in a subassembly (1) of a linkage (2) of a wiper mechanism comprising: a bearing (3), a crank (5) articulated on the bearing (3) having a first end (51) connected to the bearing (3) and a second end (53) including a ball joint (7), and a link (9) one end of which is connected by the ball joint (7) to the crank (5), characterized in that at least the crank (5) includes a first through-opening and in that the subassembly (1) comprises a locking element (11) intended to be positioned in the first through-opening and configured to block relative movement between the link (9) and the crank (5).

A wiper motor control circuit carries out control in which a driving circuit generates, and supplies to a wiper motor, a voltage that eliminates deviation between a target speed and an actual speed of an output shaft. In a case in which a state in which the deviation between the target speed and the actual speed is greater than or equal to a predetermined threshold value continues for a predetermined time or more, the wiper motor control circuit carries out control that lowers the target speed and in which the driving circuit generates, and supplies to the wiper motor, a voltage that eliminates deviation between the lowered target speed and the actual speed of the output shaft.

A wiper system for a vehicle includes: a glass wiper disposed on a window glass of a vehicle; a motor providing driving power to the glass wiper; a camera capturing images of surroundings of the vehicle; and a camera wiper disposed on a camera lens of the camera and connected to the motor by a linkage to operate in association with the glass wiper such that the camera wiper swings back and forth over the camera lens while the glass wiper swings back and forth over the window glass.

A wiper drive device includes: a drive member that is configured to cause a wiper blade to wipe a region of a windshield as a wiping operation, the region of the windshield including a to-be-imaged region of the windshield, the to-be-imaged region being included in a field of view of a camera which images a predefined imaging range near a vehicle through the windshield; and a stop section that is configured to stop the wiper blade in an outside region in response to that an anomaly that hinders the wiping operation occurs while the drive member causes the wiper blade to perform the wiping operation on the windshield, the outside region being a region of the windshield outside of the to-be-imaged region.

A work vehicle comprising: a cab, an inside of which is a cockpit, having a window portion; a vehicle body having a passage on a periphery of the cab; a front lateral wiper provided so as to be rotatable around a first axis and along the window portion, and rotating around a second axis that extends in a different direction with the first axis in a movement range between a normal position that is in contact with the window portion and a rising position separated from the window portion; and a passage fence extending along an outer edge of the passage. The passage fence is configured to open upward with penetrating the passage fence inwardly and outwardly, and a part of the passage fence has an opening that includes the movement range of the front lateral wiper.

Fixing device (30) for a windscreen wiper actuation linkage system, this device comprising a plate (32) intended to be fixed onto a vehicle body (36), and at least one locking member (34) intended to cooperate with said body to lock the fixing of the plate onto the body, characterized in that said plate is configured to be displaced in translation in the joint plane with said body, and in that said locking member is mobile, deformable or displaceable from an unlocking position to a locking position.

A cab of a work vehicle includes a front windshield that extends in a vehicle width direction; front lateral windshields that extends diagonally rearward and is connected to both sides of the front windshield in the vehicle width direction via ridgelines, and a rear-end edge of each front lateral windshield extending in a vertical direction being gradually separated from the ridgeline of each front lateral windshield while extending downward; a front lateral wiper that is disposed so as to be rotatable around an upper axis that is disposed above each front lateral windshield and so as to be rotatable along each front lateral windshield; an upper drive device that is configured to reciprocally rotate the front lateral wiper around the upper axis between a rear position in and a front position.

The present invention comprises an AS-side wiper motor 40 including an AS-side output shaft 83 that is rotated in forward and backward directions and a link mechanism 60 constituted by a four-bar link. The AS-side wiper member 50 is configured to wipe in a first AS-side wipe range 11b by a pivotal movement of the AS-side output shaft 83 in a first angular range SA1, and wipe in a second AS-side wipe range 11c by a pivotal movement of the AS-side output shaft 83 in a second angular range SA2 that differs from the first angular range SA1. The wipe range of the AS-side wiper member 50 can thus be switched between the first AS-side wipe range 11b and the second AS-side wipe range 11c by controlling an angular range, in which the AS-side output shaft 83 is pivotally moved, to be in the first angular range SA1 or the second angular range SA2 that differ from each other. In addition, a size of the wipe range can be adjusted by controlling a pivot angle of the AS-side output shaft 83 in forward and backward directions.
