Patent ID: 7726225

Claim:
A miter saw comprising: a base section having an upper surface on which a workpiece is mounted, the base section defining a frontward/rearward direction and a lateral direction perpendicular to the frontward/rearward direction; a saw blade section rotatably supporting a circular saw blade, the circular saw blade having a rotation axis extending in the lateral direction; a holder shaft extending in a direction perpendicular to the rotation axis and in the frontward/rearward direction; a holder tiltable about the holder shaft in the lateral direction relative to the base section; two guide bars disposed slidable with respect to the holder and extending in the frontward/rearward direction in parallel to each other; a support segment fixed to the guide bars and supporting the saw blade section; a pivot shaft disposed between the saw blade section and the support segment and extending in parallel with the rotation axis, the saw blade section being pivotable about the pivot shaft and movably supported to the support section toward and away from the upper surface; and a holder fixing mechanism that fixes a tilting posture of the holder relative to the base section, the holder fixing mechanism comprising an operation member supported to the holder and provided with a rotatable shaft passing through a space between the two guide bars; wherein the rotatable shaft of the operation member extends in a direction perpendicular to the holder shaft and in a direction substantially parallel with opposite side surfaces of the circular saw blade.
