Description

[Detailed description of the invention] This invention relates to a holding device for a wiper pivot for a vehicle, and particularly for a wiper pivot for a vehicle in which the swing axis of the wiper pivot is tightened and fixed at an angle of inclination other than right angles to the vehicle body plate. The present invention relates to an improvement of a holding device.

Conventionally, as a holding device for a vehicle wiper pivot, those shown in FIGS. 1 and 2 have been applied. Namely, 1 is a vehicle body plate, 2 is a swing shaft constituting a wiper pivot, 3 is a bearing cylinder thereof, 4 is a collar plate, 5 is a swing lever, 6 is a cap-shaped packing, 7 is a cap-shaped washer, 8 is a nut, 9 is a seal cap, and after inserting the wiper pivot into the mounting hole drilled in the vehicle body plate 1, a packing whose mounting surface is inclined is attached to the bearing cylinder 3 from the outside of the body plate 1. When the washer 6 and the washer 7 are fitted and the nut 8 is screwed, the pivot is held at an inclination angle other than right angles to the vehicle body plate due to the interposition of the gasket 6 and the washer 7.

However, in the above configuration, the nut 8
During the tightening operation, the washer 7 fitted into the packing 6 may follow the nut and rotate, resulting in positional deviation.

Therefore, in the above structure in which the pivot shaft 2 is assembled with an inclination angle other than right angles to the body plate 1 in order to improve the wiping performance of the wiper, the rotational position of the washer 7 is shifted. In this case, the wiper blade is not evenly pressed against the glass surface, causing a wiping error.

Therefore, in order to prevent the washer 7 from shifting its position when tightening the nut, it is fixed with adhesive, a hole is made on the washer side and a protrusion on the packing side is inserted and fixed, or the washer and the packing are fixed. Methods such as fixing with insert molds have been adopted, but methods of fixing with adhesive have the disadvantage that the washer cannot be held in a fixed position due to shock during tightening and peeling due to flexure. Also, the method of drilling holes in the washer and incorporating protrusions on the seal is relatively effective when there is a contact surface with a large part, but in the case of small parts, the protrusion on the seal alone may not have sufficient fixing force. ,
Furthermore, the insert molding means of packing and washing gives an unattractive appearance, and all of the above-mentioned means are poor in practicality.

This invention was made in order to solve the above-mentioned problem, and the swing axis of the pivot that is inserted into the vehicle body plate is made perpendicular to the body plate by using a washer and a packing whose mounting surface is inclined. The main object of this invention is to provide a holding device for a vehicle wiper pivot which is tightened and held at an angle of inclination other than the above, and which prevents the washer from being in a rotational position when a nut is tightened.

Hereinafter, this invention will be explained in detail based on FIGS. 3 to 6, which show examples thereof.

In FIG. 3, 10 is a cap-shaped washer, and 11 is a cap-shaped packing, which correspond to the washer 7 and packing 6 in FIG. Among the perforated top plate 10a, shroud plate 10b, and collar plate 10c forming the washer 10, downwardly bent protrusions 10d are formed at multiple locations on the perforated top plate 10a,
This protrusion 10d is fitted into a receiving hole 11a formed in the packing 11, and the engagement action of this fitting portion prevents the washer 10 from shifting when tightening the nut 8 (see Fig. 1). It's becoming like that.

The one shown in FIG. 4 has downward protrusions 10d formed by punching at a plurality of locations on the perforated top plate 10a, and the protrusions 10d are connected to the receiving holes 11 of the packing 11.
It is fitted in a.

In the case shown in FIG. 5, downward protrusions 10a are formed by drilling at a plurality of locations on a perforated top plate 10a of a washer 10, and the protrusions 10a are fitted into receiving holes 11a of a packing 11.

What is shown in FIG. 6 is the collar plate 1 of the washers 10.
Downward protrusions 10e are formed by drilling at multiple locations on 0c, and the protrusions 10e are attached to the packing 1.
It is fitted into the receiving hole 11b of No. 1.

The configurations shown in FIGS. 4 to 6 can also provide the same nut displacement prevention effect as that shown in FIG. 3.

As described above, according to this invention, the wiper pivot, which consists of a swing shaft and a threaded shaft cylinder that supports it, is inserted into the vehicle body plate from the inside, and attached to the shaft cylinder that protrudes outside. A holding device for a vehicle wiper pivot in which a nut is screwed through a cap-shaped packing having an inclined surface and a cap-shaped washer, and a swing shaft is held at a predetermined angle of inclination with respect to a body plate. A protrusion is integrally formed in a part, and the protrusion is fitted and locked into the receiving hole on the packing side, so that the fitting and locking action prevents the washer from shifting when tightening the nut. , the effect of maintaining the tilt angle of the swing axis with respect to the body plate can be obtained, and the wiper wiping performance can be further improved.
