Abstract:
Two different eccentric shaft portions are formed on a secondary shaft. A contact plate has two different contact portions which are selectively brought into contact with two eccentric shaft portions of the secondary shaft. The contact plate is attached to a guide sleeve. A plunger is slidably coupled in the guide sleeve. A saw blade, attached to a front end of the plunger, causes an orbital motion according to a phase difference between two eccentric shaft portions regardless of attached direction (i.e., normal or upside-down) of the saw blade.
