[Problems to be Solved by the Invention] In order to improve work efficiency,
When the mop width was widened, large turning resistance was added to the turning side of the mop when the aircraft turned, and the other side might float up, leaving some areas uncleanable. Also, in order to prevent this floating, it is sufficient to push down the mop with a strong elastic force, but this means that the sliding load becomes large and a large traction force is required, and the mop wears quickly. There are drawbacks. The present invention is intended to solve such problems and provide a reliable cleaning device that does not float even when turning.

[0004]

[Means for Solving the Problems] At the rear of a towing vehicle 1, a base portion of a support rod 2 extending rearward is pivotally supported 3 so as to be vertically movable, and a spring 4 is used to urge the support rod 2 downward. At the rear of the supporting rod 2, a central portion of the mop 5 having a width wider than that of the towing vehicle 1 which is wider than the towing vehicle 1 for cleaning while sliding on the floor is attached to the supporting rod 2 and further slides on the supporting rod 2. A configuration of a towed floor cleaning device in which a pair of left and right connecting rods 8 are connected between a sliding body 7 which is freely elastically urged backward by a spring 6 and left and right side portions of a mop 5. To do.

[0005]

When the towing vehicle 1 is driven, the mop 5 connected to the rear part of the supporting rod 2 pivotally supported at the rear part of the towing car 1 so as to vertically move the base 3 is connected to the mop 5. Glide across the surface for cleaning. In this cleaning work, the support rod 2
Is urged downward by a spring 4, and the supporting rod 2
It is possible to apply a proper pressing force to the mop 5 whose central portion is connected to the rear portion and perform a reliable cleaning operation.

[0006] When performing the turning operation of the towing vehicle 1,
A large sliding load is applied to the turning side of the wide mop 5, and the other side tries to float up, but the sliding body 7 is slidable on the supporting rod 2 and is springed backward by the spring 6 on both the left and right sides of the mop 5. Since the left and right connecting rods 8 and 8 are connected to each other, the mop 5 on the side to be floated is pushed down by the elastic force of the spring 6 through the connecting rod 8 to surely contact the floor surface. It can be hit and cleaned.
