[Example] Next, an example embodying the present invention will be described with reference to the attached drawings to provide an understanding of the present invention.

Here, FIG. 1 is a plan view of a state in which a rear confirmation device of a towing vehicle according to an embodiment of the present invention is installed, and FIG.
The figure is a partial plan view of a section A in FIG. 1.

As shown in FIG. 1, the rear confirmation device for a towing vehicle according to an embodiment of the present invention includes rear viewing mirrors 19 and 20 provided diagonally in front of the outside of the front corner of the trailer 18, and It has auxiliary mirrors 21 and 22 attached to both sides.

The rear viewing mirrors 19 and 20 are convex mirrors, and have a substantially rectangular size of 15 cm in width and 30 cm in height. It is attached to arms 23 and 24 made of U-shaped pipes attached to the main body of the trailer 18 so as to be able to swing freely, and its angle can be adjusted as necessary. As shown in the figure, it is attached to the outer front part of the side plate of the trailer 18, and the third
The vertical line portion 17) in the figure is visible as indicated by arrow a.

The above-mentioned auxiliary mirrors 21 and 22 are made of plane mirrors, and have a size of about 30 cm in the vertical direction and 60 cm in the horizontal direction, and are fixed to both ends of the front surface of the trailer 18, substantially parallel to the front plate 25 of the trailer 18. ing. Note that it is also possible to make one end of the auxiliary mirrors 21 and 22 a hinge structure, and provide an adjustment mechanism at the other end to adjust the mounting angle, thereby further widening the viewing angle. becomes possible.

Since the rear confirmation device of this towing vehicle is installed as described above, what is on the rear side of the trailer 18 is reflected in the rear visibility mirrors 19 and 20, as shown in FIGS. The rear viewing mirrors 19 and 20 can be reflected on the auxiliary mirrors 21 and 22, respectively.

The present invention is also applicable to buses.

Furthermore, in the above embodiment, the arms 23 and 24 for attaching the rear view mirrors 19 and 20 are fixedly attached to the trailer 18, but there is a hinge (or other pin) that rotates at the base of the arm.
It is also possible to attach the rear viewing mirrors 19 and 20 to the inside when not in use, and to attach a drive source such as an extendable cylinder to the arm so that it can be accessed from the driver's seat. It is also possible to control.

[Effect of the invention] As is clear from the above explanation, the rear confirmation device for a towing vehicle according to the present invention includes a rear viewing mirror provided diagonally in front of the outside of the front corner of the trailer, and a rear viewing mirror provided on the front side of the trailer. The sides of the trailer can be seen from the driver's seat through the auxiliary mirrors provided on both sides of the trailer, so the driver can see the blind spots of the trailer when turning right or left. As a result, even if there is an obstacle on the rear side when reversing the vehicle, it can be seen from the driver's seat, which greatly helps reduce accidents.
