A roller for a portable cutter capable of adjusting a subjective working distance and height between a user and the ground is provided to help any non-skilled person including women and the elderly to use it with easiness. A roller(5) for a portable cutter is comprised of a shaft axis(500) for the instrumentation of a bolt or a nut connecting a cutter blade(3) onto a rotational axis(2) of a driving unit(1) with an incremental bolt or an incremental nut, to which a friction piece is combined; a rotating casing held the ground for encompassing the axis; and a washer for interconnecting the shaft axis(500) and the friction piece with the casing. A first washer is connected to the lower end of the rotational axis(2), followed by the cutter blade(3) and a second washer(220). |
