PROBLEM TO BE SOLVED: To provide a keyless blade clamp which is easy to manufacture, simple to use, and whose service life is prolonged. SOLUTION: A reciprocating tool, for example, a reciprocating saw, comprises a housing; a spindle 22 having an end part 50 designed to reciprocatively arrange in the housing and receive a saw blade; a blade clamp mechanism coupled to the spindle 22 and mounting the saw blade on the spindle 22. The blade clamp mechanism comprises an actuating member 38 mounted on the end part 50 of the spindle and movable to the spindle 22 between an engaging position and a non-engaging position; and a lock member 30 movable to the spindle 22 between a lock position workably related to actuating members 38 and 40 and locking the saw blade at the spindle 22 and a non-lock position wherein the saw blade is released. Through movement of the actuating members 38 and 40 from a non-engagement position to the engagement position, the locking member 30 is forcibly moved from the non-lock position to the lock position. Through movement of the actuating members 38 and 40 from the engagement position to then on-engagement position, the lock member 30 is forcibly moved from the lock position to the non-lock position. |
