Work supporting device mountable on a worktable of a circular sawing apparatus
 A work supporting device includes an elongated body, an extension plate and a locking unit. The elongated body has elongated first and second sections and an intermediate curved section. A gap is formed between the first and second sections. The curved section is indented from the work supporting faces at the gap. The first section has a first end distal from the second section and a second end proximate to the second section. The extension plate is connected pivotally to the first section of the elongated body. The extension plate is pivotable about an axis transverse to the first section between a first position where the extension plate extends into the gap in order to shield at least a part of the gap, and a second position where the extension plate extends beyond the first end of the first section of the elongated body in order to prolong the length of the first section from the first end of the first section. The locking unit is provided for releaseably locking the extension plate in one of the first and second positions.
