Abstract:
A scribe device comprising:a body (10) having an abutment portion (55a); a holder (20) having another abutment portion (25a); a vibration actuator (40) supported between said abutment portion of said body and said abutment portion of said holder and generating vibrations in opposing directions thereof; an abutment member (30) retained by one end portion of said holder for transmitting the vibrations, which have been given to said holder from said vibration actuator, to a workpiece (100); and a resilient member (61, 62) for movably supporting said holder on said body for movement in the vibration directions, said resilient member being disposed between said vibration actuator (40) and said abutment member (30) and resiliently deformably only in the vibration directions, and said resilient member biasing said holder (20) against said vibration actuator (40), thereby applying a pre-load to said vibration actuator; wherein an adjustment screw (55) is threadingly engaged with said body (10), a distal end portion of said adjustment screw (55) being provided as said abutment portion of said body, the pre-load applied to said vibration actuator (40) being adjusted by adjusting a screwing amount of said adjustment screw.
