When the anti-skid device for a track according to the present invention is used, the mounting member is mounted so as to be sandwiched in the groove of the moving track for movement in the width direction. When the work vehicle provided with the traveling endless track is run, the endless track anti-slip device also rotates together with the traveling endless track. At a position where the non-slip member does not hit the road surface, the non-slip member rises from the groove portion higher than the step portion of the moving endless track. When the non-slip member hits the road surface along with the rotation of the moving endless track, the anti-slip member is tilted in the opposite direction to the traveling direction and is sandwiched between the stepped portion on the tilted side and the road surface. Thereby, the non-slip member increases the frictional force and can prevent the moving endless track from slipping on a frozen road surface or the like. When the non-slip member moves away from the road surface, the anti-slip member resiliently rises again from the groove. For this reason, when the work vehicle travels in the opposite direction, the non-slip member hits the road surface and is tilted in the direction opposite to the traveling direction, and is sandwiched between the stepped portion and the road surface to increase the frictional force, so that the moving The track can be prevented from slipping on a frozen road or the like.

A work vehicle according to the present invention is a work vehicle that travels by rotating a traveling endless track having alternating steps and grooves extending in the width direction on the outer periphery, and has flexibility. A non-slip member fixed to the groove so as to rise from the groove higher than the step, and having a length to come into contact with the upper surface of the step on the side that has fallen when it has fallen in the direction perpendicular to the width direction. It is characterized by the following.

When the work vehicle according to the present invention travels, the non-slip member also rotates together with the moving endless track.
At a position where the non-slip member does not hit the road surface, the anti-slip member rises from the groove portion higher than the step portion of the moving endless track. When the non-slip member hits the road surface along with the rotation of the moving endless track, the anti-slip member is tilted in the direction opposite to the traveling direction and is sandwiched between the stepped portion on the tilted side and the road surface. Thereby, the non-slip member can increase the frictional force and prevent the traveling endless track from slipping on a frozen road surface or the like. When the non-slip member moves away from the road surface, the anti-slip member resiliently rises again from the groove. For this reason, even when the work vehicle travels in the opposite direction, when the non-slip member hits the road surface,
The moving endless track can be prevented from slipping on a frozen road surface or the like by being tilted in a direction opposite to the traveling direction and sandwiched between the step portion and the road surface to increase the frictional force.

In the present invention, a flexible wire that stands up is suitable for the non-slip member. The endless track anti-slip device according to the present invention may be attached to a traveling endless track having no steps or grooves. The transfer endless track to be attached may be made of iron or any other material, but a rubber endless transfer endless track is particularly effective in preventing slippage.
