Title:
COUPLING DEVICE FOR DRIVING MEMBER
Document Type and Number:
Japanese Patent JPH07103248
Kind Code:
A
Abstract:

PURPOSE: To maintain rigidity in the axial direction when rotating force is transmitted under an eccentric condition between a driving shaft and an output shaft in a screwdriver device or the like so as to drive the screwdriver device under an eccentricity absorbing condition and to automatically return the screwdriver device to the original position afterward.

CONSTITUTION: A screwdriver device l is constructed in such a way as arranging a coupling member 3 between a driving shaft 2 and an output shaft 4 provided with a bit 5, and the rotation of the driving shaft 2 is transmitted to the bit 5 while the bit 5 engagingly locked in a trimmer 7. In the coupling member 3, mechanisms, which slide each other via ball slides 30, 50, are constructed between an upper base member 10 and a lower base member 70, which are individually arranged in upper and lower shafts, and a returning action via self-aligning mechanisms 20, 60 is exhibited. Under a condition, in which the bit 5 is engagingly locked to the trimmer 7, the rotational torque of the driving shaft 2 is transmitted to the bit 5, so that the rotational action to an object can be given.
