Claims

[Scope of utility model registration request]

A driver bit device comprising a driver bit which is rotatably driven and supported by a member to be adjusted so as to be able to move toward and away from the adjusted member, and a guiding protrusion is provided at a position eccentric from the center of rotation of the bit on the leading edge of the driver bit.
