Abstract: The invention relates to a windshield wiper device, particularly for a motor vehicle, comprising at least one wiper shaft (10). Prior art windshield wiper devices having predetermined breaking points exist in order to meet the high demands of pedestrian impact protection. However, the risk of these predetermined breaking points rupturing during the operation of the wiper exists in this type of windshield wiper device. In addition it cannot be guaranteed that the predetermined breaking point ruptures in the event of a pedestrian impact. Therefore, in the inventive windshield wiper device, the at least one wiper shaft (10) can be displaced under the action of a force.

Abstract: In an individual-spindle-drive type multiple twister that directly employs separate motors to drive the spindle shafts of each twisting unit, when a spindle is inserted into the housing during motor assembly, a rotor and a stator may attract each other and adhere to each other, and this attraction may prevent the spindle shaft from being correctly inserted into a target bearing, thus making it difficult to assemble the motor. A spindle shaft 4 is rotatably supported by bearings 27a and 28a mounted onto upper and lower supporting members 27 and 28. The distance A between the lower end of the rotor magnet 32 of the drive motor 10 fixed to the spindle shaft 4 and the lower end of the spindle shaft 4 is longer than the distance B between the upper end of the stator coil 31, which is fixed to the housing 34 of the drive motor 10, and the bearing 28a of the lower supporting member 28. In addition, the tip 4 of the spindle shaft 4c is tapered to facilitate insertion.

Abstract: The bearing assembly includes a synthetic resinous collar which circumscribes the tube and oscillates therewith against the inside of a metal bushing wedged within a metal housing that is bolted to the adjacent tine tube carrier arm of the reel. The bushing is constructed from a pair of generally semicircular half-sections that are abutted together to make a complete annulus when held within the housing, thereby permitting removal of the bushing from the tube by simply separating the two half-sections from one another after the housing has been slipped axially off the end of the bushing. A slit in one side of the collar permits opposed wall portions thereof to be spread apart so that the collar may likewise be removed from the tube in a transverse direction rather than requiring axial movement along the tube which would be obstructed by crop-engaging tines of the reel.

Each roller assembly comprises three rust and corrosion proof plastic components, including a stud, a bushing screwed onto the stud and a roller rotatably mounted on the bushing, and the roller assembly is secured to the liner wall by a metal screw which extends through a hole in the wall and engages the stud. A sealing gasket is disposed around the screw between the stud and the liner wall to prevent liquid in the compartment from reaching the hole and the screw. The stud has a screw-receiving threadable bore which is closed at one end so as to completely encapsulate the screw and prevent liquid from reaching it. The stud has an externally threaded shank which extends into a threaded bore in the bushing which is closed at one end.
