Abstract

PURPOSE: To eliminate local application of impact and construct a bit holder in a small size by bearing the other end of the bit holder, which holds a bit by one end, rotatably on a shaft, interposing a buffer member in this shaft bearing part, and allowing the holder to absorb the impact application when the bit makes cold blow. CONSTITUTION: When a striket 2 strikes a bit 1 with cold blow, the bit 1 is going to hop out in the axial direction, but it is prevented because the bit 1 is held by the holding part 5 at a notch in a holder 6. Further the impact of the bit 1 is applied to the holder 6, but it is transmitted to the body 3 through a buffer member 8 which is interposed between the other end of the holder 6 and a shaft 7. Accordingly no large impact will be applied to the holder 6 and the body 3, and it is possible to avoid breakage of the holder 6 and construct the holder 6 in a small size.
