In these walk-behind work machines, the main body and the work machine are attached to the underside of the handle body or support arm that extends rearward above the work machine so that the work machine can be easily attached or removed at night or in a dark place. An illumination lamp is provided to illuminate the mounting area.

It is stated in the No. In this walk-behind work machine, headlights are provided on both sides of the machine frame or handle, and are located behind the engine and substantially above the work machine, and are rotatable downward and forward. With this walk-behind work machine, the front of the machine can be illuminated by the headlight during night work, and by pointing one of the headlights towards the front of the machine and the other towards the bottom of the machine, the area under the worker's feet can be illuminated. .

る場合がある。Problems that the invention aims to solve: A snow blower in which the work equipment is mounted in front of the drive wheels.
Walk-behind work machines such as transporters and lawn mowers are often used in places with poor driving conditions (road surface conditions) such as places with many ups and downs, and when working at night in such places, it is especially important to During work, it is necessary to move forward and backward while paying close attention to one's step, and for this reason,
For vehicles that often have to back up, it may be necessary to install a light that illuminates the rear when backing up.

く、足下を適確に照明する上で難点がある。 However, it is desirable that the lever rear illumination light be installed in a position where it will not interfere with night work and is most effective. In the tiller of the above-mentioned Japanese Utility Model Publication No. 38-16209, it is possible to illuminate the feet of the worker by rotating one of the headlights and directing it downward. Since it must be freely attached to the fuselage, the mounting structure becomes complicated and the operation becomes complicated. Also, since the headlights are mounted on both the left and right outer sides of the aircraft, care must be taken to avoid contact with foreign objects on the sides during work. Furthermore, for rear lighting, one of the left and right headlights is used with one facing downward, but this headlight illuminates the feet of the worker from a position offset to either the left or right side of the aircraft, and Since a working machine is located below the headlamp, the worker's feet tend to be in the shadow of the working machine, making it difficult to properly illuminate the area under the worker's feet.

In a walk-behind work machine that is provided with a pair of left and right steering handles that extend toward each other, the upper end of each of the handles is bent rearward to form a grip part, and the left and right handles are provided in front of the grip part. A control panel is installed horizontally across the control panel, and a rear illumination light is provided below the panel and positioned forward of the rear edge to project light downward toward the rear of the grip portion, and The rear illumination light is located forward of a line connecting the driving wheels and the rear ends of the grip portion, inside two lines in the front and back direction along both sides of the aircraft body, and above the driving wheels.

い。 According to the present invention, the rear illumination light is provided between the left and right handles in front of the grip portion, so that the feet of the operator can be illuminated directly and accurately.
Moreover, this rear illumination light is protected from external forces from all directions and is mounted in a position where it does not interfere with operation. In other words, the upper part is covered and protected by the control panel, and since it is located in front of the rear edge of the panel, it is also protected from the rear. For example, when a worker pushes the machine with his body, his body hits the light. There is no need to apply force to this. In addition, since the light is located closer to the handle than the line connecting the rear end of the grip and the rear end of the drive wheels, even if the aircraft is tilted backwards until the rear end of the grip touches the ground, the light will remain on the ground. It will not be damaged by contact with. Furthermore, since the light is located between the left and right handles and does not protrude sideways, there is no risk of damage due to contact with foreign objects on the side during work. Furthermore, since the light is located above the aircraft, pebbles and dirt thrown up by the drive wheels are unlikely to hit the light, and the light is mounted on the underside of the control panel. Therefore, it does not interfere with the operation of control levers and switches provided on the top surface of the panel.

Located in a location protected from external forces from any direction. First, the rear light 39 is covered from above by the control panel 29 and is protected against external forces from above. It is attached to the back side of the rear surface 29a of the control panel 29 via the bracket 40, and is located forward of the vertical line _l1 (FIG. 1) passing through the rear edge of the rear surface 29a, so that the operator can easily operate the snow blower 1. Even when pushing the entire body forward, the body will not touch the rear light 39 and apply force to it. Also, rear light 39
is located closer to the handle 23 than the line l ₂ (Fig. 1) connecting the rear end of the grip 24 and the rear end of the drive wheel 9, so tilt the machine 3 backward until the rear end of the grip 24 touches the ground. However, the rear light 39 never comes into contact with the ground. Furthermore, the rear light 39 is located between the left and right handles 23, 23, and is located along a line along both sides of the aircraft body 3.
Since it does not extend laterally from l ₃ and l ₃ (Figure 3),
There is no risk of coming into contact with foreign objects on the side during work. Furthermore, since the rear light 39 is located sufficiently above the line l ₄ (Fig. 1) extending rearward from the top of the drive wheel 9, pebbles and mud thrown up by the drive wheel 9 are illuminated by the rear light. It almost never hits light 39.
