As described above, the wiper structure of the side window of the vehicle of the present invention is configured.

  Next, the case where the wiper structure of the side window of the vehicle of the present invention configured as described above is used will be described with reference to FIGS.

  For example, on a rainy day, when the glass 12 of the side window 1 of the vehicle has water droplets, when the drive worm 221 is rotated by driving the drive motor 22 of the wiper drive device 2, the drive worm 221 engages. The drive worm wheel 232 is interlocked, the drive worm wheel 232 is interlocked with the passive worm 233 via the support shaft 230, and the passive worm 233 is interlocked with the passive worm wheel 234 on the other support shaft 231. The passive worm wheel 234 interlocks the drive gear 235 via the support shaft 231, the drive gear 235 interlocks the passive gear 26 on the spindle 24, the passive gear 26 interlocks the spindle 24, and the spindle 24, the connecting rod 3 is interlocked.

  When the connecting rod 3 is driven, the wiper 4 is interlocked. Therefore, the wiper 4 is displaced along an arc line with the spindle 24 as an axis, and the wiper 4 is made of a flexible material and elastically formed therein. When the blade 40 is provided and is separated from the upper edge of the side window 1 of the vehicle, the outer end is straightened little by little by the elastic recovery of the internal elastic blade 40 (see FIGS. 7 and 8), and the spindle 24 When the wiper 4 is displaced to the lower edge of the side window 1 of the vehicle, the projecting body 271 of the stopper 27 of the spindle 24 comes into contact with one end edge of the stopper 213 on the outer side of the cover 21, so that the spindle 24 cannot be rotated. In this state, the torque of the drive motor 22 increases, and when the torque increases to a certain level or more, the drive motor 22 temporarily stops and then rotates in the reverse direction.

  As the drive motor 22 rotates in the reverse direction, the spindle 24 also rotates in the reverse direction. Therefore, the wiper 4 is also interlocked and displaced upward in the reverse direction, and the wiper 4 is displaced upward. When the water droplets on the glass 12 of the side window 1 of the vehicle are surely wiped off and the wiper 4 comes into contact with the upper edge of the side window 1 of the vehicle, the protrusion 271 of the stopper 27 on the spindle 24 21 is in contact with the other end edge of the stopper 213 on the outer side of the spindle 21, so that the spindle 24 cannot rotate, and the drive motor 22 rotates in the opposite direction after the torque is increased again and stopped. 4 comes to be displaced downward.

  By the reciprocating operation as described above, the water droplets on the glass 12 are surely wiped off by the wiper surface 41 of the wiper 4, the glass 12 of the side window 1 of the vehicle is cleaned, and the driver also uses the side mirror 5. It is possible to clearly grasp the surrounding situation and improve driving safety.

  When the wiper 4 is not used, the drive motor 22 displaces the wiper 4 so as to contact the upper edge of the side window 1 (that is, in the storage space 53 of the connecting seat 50 of the side mirror 5). As shown in FIGS. 5 and 9, the passive gear 26 on the spindle 24 rotates slightly by being interlocked by the drive gear 235.

  At this time, the spindle 24 does not rotate because the wiper 4 comes into contact with the protruding edge 52 in the connecting seat 50 of the side mirror 5 and cannot be displaced. However, when the passive gear 26 rotates, the fitting body 241 on the spindle 24 is detached from the fitting groove 261 in the storage space 260 of the passive gear 26, and at this time, the fitting body 241 is inside the storage space 260. Abutting against the wall surface, the spindle 24 is pushed forward to compress the elastic member 25 (see FIG. 9), and the connecting rod 3 and the wiper 4 are moved forward by the spindle 24. Therefore, the wiper 4 wiper surfaces 41 separate from the glass 12 of the side window 1 of the vehicle to form a gap 6.

  By adopting such a configuration, it is possible to prevent the wiper 4 from coming into contact with the glass 12 over a long period of time, and the wiper 4 is softened due to high-temperature sunlight, or the oil quality of the glass 12 is reduced. The penetration of the capillary tube can be prevented, the glass 12 is kept clean, and the useful life of the wiper 4 is improved.

  When the wiper 4 is stored, the outer end of the wiper 4 is brought into contact with the protruding edge 52 in the connecting seat 50 of the side mirror 5, so that the outer end of the wiper 4 extends along the extending portion 51 of the connecting seat 50. The wiper 4 is housed in the housing space 53 of the connecting seat 5 and is not exposed, thereby improving the aesthetic appearance of the side window 1 of the vehicle.

  Further, when the wiper 4 is used again, the wiper driving device 2 is driven by the drive motor 22 and the passive gear 26 is rotated again, whereby the fitting groove 261 of the passive gear 26 is formed on the fitting body 241 of the spindle 24. The spindle 24 is urged to the original position by the elastic recovery of the elastic member 25, and the fitting body 241 of the spindle 24 is fitted and positioned in the fitting groove 261 of the passive gear 26, so that the wiper 4 The wiper surface 41 comes into contact with the glass 12 again, and with the above structure, the wiper 4 is displaced to cleanly wipe off water droplets on the glass 12 and provide a practically excellent one that is very easy to use.
