<p>A device for a motorized saw wherein the saw guide bar consists of a reciprocating toothed saw blade (13) and a relative to this stationary support plate (12). One circular disc (14) is loosely laid into an elongated recess (15) in the support plate (12) such that it is movable relative to the support plate (12) as well as to the saw blade (13) and therefore the friction against the support plate is diminished.</p> |
