The invention relates to a saw blade structure of a chain saw that comprises a saw blade (121) for a saw chain (141), a fastening part (122) for fastening the saw blade to a frame part (360) of the chain saw, the frame part (360) being movably fastenable to a boom (110). The saw blade structure (120) also comprises a support structure (200) in the longitudinal direction of the saw blade (121) for bracing the saw blade (121) in such a manner that the support structure (200) is fastenable at least at one point to the side surface of the saw blade (121) and at least at another point to the frame part (360). In addition, the invention relates to a chain saw (112) that comprises said saw blade structure (120) and saw chain (141) arranged to the saw blade (121). In addition, the invention relates to a work machine that comprises a boom (110), to which said saw blade structure (120) or chain saw (112) is fastened. In addition, the invention relates to an accessory for the saw blade structure of the chain saw, wherein the accessory (200) is a support structure (200) bracing the saw blade (121) and fastenable to the side of the saw blade (121) of the saw blade structure, and the support structure (200) is fastenable at least at one point to the side surface of the saw blade (121) and at least at another point to the frame part (360) of the chain saw, which is movably fastenable to the boom (110). |
