Description

  The present invention relates to an anti-slip device for a motorcycle that is attached to a tire of a motorcycle (such as an auto bike or a bicycle) to prevent slippage on a snowy road.

Conventionally, a slip preventer for a band-shaped tire that is mounted on a tread surface of an automobile tire with a required interval in a circumferential direction is disclosed in Japanese Utility Model Laid-Open No. 62-36904. On the other hand, an anti-slip band that is attached to a tire with a rim such as an auto bike or a bicycle to prevent slip is disclosed in Japanese Patent Laid-Open No. 2001-39131.
By the way, the former band-shaped preventive tool main body cannot be fastened to both ends endlessly, and the latter anti-slip band is a metal fitting consisting of a tightening main body part and a hook. There is a risk of loosening when a fluctuation in tension occurs, and if the band itself retains elasticity, the resistance at the time of slip prevention is relaxed and its effectiveness is reduced. In addition, the band has a rivet caulking head to which the spike is fixed so that it is indented into the tread surface of the tire, but in this case as well, there is no elastic force in the fastener itself, so the tire air pressure has decreased. Sometimes there is a risk of slipping on the tire tread. In addition, such a fastening tool has a narrow degree of freedom in use, such as being unable to be used when the length of the peripheral surface of the tire including the rim, that is, the target vehicle type is changed.
