<p>The present invention relates to a bobbin for a snowplow wire and a snowplow and, more specifically, to a bobbin for a snowplow wire and a snowplow which prevent a wire and parts from being damaged by releasing the wire wound around the bobbin if force larger than or equal to predetermined force is applied to the wire wound around the bobbin even when power of a motor rotating a snow removing shovel is stopped. The bobbin for the snowplow wire comprises a rotor comprising a wiring part formed with a both-sides through insertion hole and escaping preventive pieces with diameters larger than the diameter of the wiring part, wherein a plurality of first toothed gears is formed along the edge of the escaping preventive pieces on one side; a stator comprising an insertion bar formed at the insertion hole of the wiring part, a combining piece formed with a second toothed gear engaged with the first toothed gears, and a power receiving part formed on one side of the combining piece and receiving power from a motor; a stopper formed along the inner diameter of the side of the insertion hole at which the first toothed gears are formed; a fixed socket which is combined with the end part of the insertion bar, combines the rotor to the stator, and ensures a moving distance to allow the engagement of the first toothed gears of the rotor and the second toothed gear of the stator to be released; and a spring which surrounds the outer circumference of the insertion bar on the insertion hole and elastically supported between the stopper and the fixed socket.</p> |
