To provide a crasher for branches and leaves capable of applying an elastic force of a spring to a drawing roller without applying time or labor, at the same time, capable of easily carrying out a maintenance of the drawing roller.

The drawing roller keeps both the ends of rollers axially supported by a pair of supporting members 58 and is dropped into a cutout part 57B from the upper part. An ejected plate 80 with a through-hole 81 is provided at the back side of a cover 61, a rod 70 provided with a spring 90 is secured to be freely rotatable at the supporting member 58A and is inserted into the through-hole 81. Thereby, without time and labor, for demounting the spring 90, only by lifting a cover 61 from a state that the cover 61 is wholly closed, an action applied to the supporting member 58 by an elastic force of the spring 90 is automatically loosed. Additionally, an action raising up the supporting member 58 can be done by such a simple action. Furthermore, only by a simple action to close the cover 61, an elastic power of the spring 90 can be automatically applied to a draw-in roller.
