  The space | interval of the wheel 9a (10a) of the movable part 6a and the wheel 9b (10a) of the movable part 6b means the space | interval of the centers of the left-right direction (width direction) of each wheel 9a (10a), 9b (10a). ing. Similarly, the distance between the left and right rear wheels 52 of the towed vehicle 50 means the distance between the centers of the rear wheels 52 in the left-right direction (width direction). Further, the width direction of the wheels 9a, 9b is a left-right direction facing the traveling direction (front) of the towing vehicle 1 as shown in FIG.

  In the auxiliary cart 2 configured as described above, as shown in FIGS. 2A and 2B, between the wheels 9a and 10a (outer wheels) of the movable portion 6a and the wheels 9b of the movable portion 6b, Illumination devices 15 (lighting fixtures 21) are respectively disposed between 10b (outer wheels). That is, the illumination devices 15 are arranged on the left and right sides of the auxiliary carriage 2 respectively.

  The illumination device 15 having the same structure can be attached to the body members 20a and 20b of the mounting members 11a and 11b of the movable parts 6a and 6b. That is, the illumination device 15 attached to the movable part 6a can be attached to the movable part 6b by changing the direction around the vertical axis by 180 degrees. Therefore, the illumination device 15 can be attached to either of the left and right movable parts 6a and 6b of the auxiliary carriage 2.

  As shown in FIG. 3 (b), the lighting device 15 attached to the movable portion 6a on the right side of the auxiliary carriage 2 does not protrude beyond the right side (outside) of the wheels 9a and 10a. It arrange | positions in the range of the left-right direction of the trolley | bogie 2. As shown in FIG. Similarly, the illumination device 15 attached to the movable portion 6b does not protrude from the left side (outside) of the wheels 9b and 10b of the auxiliary carriage 2 and is disposed within the range of the auxiliary carriage 2 in the left-right direction.

  In the towing vehicle 1 (FIG. 1) that pulls the towed vehicle 50, the lighting device 15 is installed on the auxiliary carriage 2 on which the towed vehicle 50 is placed. The illuminating device 15 includes a luminaire 21 (light emitting unit 29) that protrudes upward from the upper ends of the wheels 9 a (10 a) and 9 b (10 b) that are the outer wheels of the auxiliary carriage 2. Therefore, from the vehicle facing the towing vehicle 1 or the vehicle following the towing vehicle 1, the lighting fixture 21 (light emitting unit 29) that emits light is visible above the wheels 9a (10a) and 9b (10b). Further, when the light emitting unit 29 emits light, the presence of the wheels 9a (10a) and 9b (10b) of the auxiliary carriage 2 is easily recognized by the driver of the vehicle around the towing vehicle 1.

  Further, since the auxiliary cart 2 is separated from the vehicle body 1a and the front wheel mounting portion 1b of the towing vehicle 1, the auxiliary cart 2 is easily overlooked by the driver of the vehicle around the towing vehicle 1. If the driver of the vehicle around the towing vehicle 1 overlooks the auxiliary carriage 2, the surrounding vehicle may come into contact with the wheels 9 a (9 b) and 10 a (10 b) that are the outer wheels of the auxiliary carriage 2.

  Therefore, in the auxiliary carriage 2 according to the present embodiment, the lighting device 15 is arranged near the wheels 9a (9b) and 10a (10b) so as to call attention to the drivers of the surrounding vehicles. Thereby, the driver of the surrounding vehicle recognizes the illumination device 15 and also recognizes the presence of the wheels 9a (9b) and 10a (10b) illuminated by the illumination device 15. As a result, the surrounding vehicle is prevented from contacting the auxiliary carriage 2 (particularly, the wheels 9a (9b) and 10a (10b)).

  In the present embodiment, the case where the light emitting unit 29 protrudes above the upper ends of the wheels 9a (10a) and 9b (10b) has been described. However, the light emitting unit 29 is not necessarily limited to the wheels 9a (10a) and 9b (10b). It does not have to exceed the upper end of. In this case, for example, a member such as a mirror that reflects light such as a mirror is provided on the main body member 20a so that light emitted from the light emitting unit 29 is scattered around. Alternatively, the movable parts 6a and 6b themselves may be made of a material that easily reflects light, or may be coated (coated) with a material that easily reflects light. Thereby, the light emitted from the light emitting unit 29 is reflected on the main body member 20a and the like and easily spreads around the towing vehicle 1. Therefore, the light emitted from the light emitting unit 29 is reflected and indirectly recognized by the driver of the vehicle around the towing vehicle 1, and the presence of the wheels 9a (10a) and 9b (10b) is recognized.

  The lighting device 15 can be attached to and detached from the lighting fixture mounting portion 25. That is, for example, the old lighting fixture 21 attached to the lighting fixture mounting portion 25 can be replaced with a new lighting fixture 21. Moreover, the lighting fixture 21 of a different luminescent color can also be exchanged and used.

  Moreover, although this embodiment demonstrated the case where the movable parts 6a and 6b of the auxiliary cart 2 had wheels 9a, 10a, 9b, and 10b only on the left and right sides, the wheels were placed on the left and right sides of the movable parts 6a and 6b. Even if it has, it does not become an obstacle at the time of implementing this invention. That is, a wheel may be provided on the inner side in the left-right direction of the movable portion 6a (6b). The wheels on the inner side in the left-right direction are not likely to come into contact with the surrounding vehicle of the towing vehicle 1. What is necessary is just to arrange | position in the position lined up.

  Moreover, although this embodiment demonstrated the case where the several outer wheel (wheel 9a, 10a) was arrange | positioned along with the advancing direction of the towing vehicle 1, even if it is a case where there is one outer wheel, this book The invention can be practiced similarly. That is, when one wheel 9a, which is an outer wheel, is provided on each of the left and right sides of the auxiliary cart 2, the wheel 9a is in front of or behind the wheel 9a and in the traveling direction of the towing vehicle 1. The lighting device 15 (lighting fixture 21) is arranged at the position where it is lined up.
