Abstract
A jig saw includes a housing and a drive shaft disposed within the housing and driven to perform a predetermined motion. A holder is mounted on the drive shaft and includes an operation member operable between a fixing position and a releasing position for fixing and releasing a saw blade, respectively. A cover is mounted on the housing and is movable between an open position and a closed position for uncovering and covering the holder, respectively. An interlocking mechanism is provided for interlocking between the operation member and the cover such that the operation member is moved from the fixing position to the releasing position when the cover is moved from the closed position to the open position.
