Abstract
A chuck mechanism is described, which is easy to handle with a chuck clamping handle of increased diameter and is capable of achieving smooth movement of its reciprocally movable portion of reduced weight and assures safe operation with the least exposure of outwardly moving portion. Rotating a knurled portion of a body case rotates an intermediate transmission member which in turn rotates a slide shaft stopping member to tighten or loosen its engagement with a slide shaft, causing clamping or releasing of a collet chuck. The slide shaft, slide shaft locking member, chuck and a saw can reciprocally move as a single unit.
