To provide a honing head of a flexible structure, applying elastic force to a grinding wheel loading surface of a wheel spindle stock sliding in a slit.

In this honing head, a plurality of slits 22 are provided to pierce extending from the inner surface of the head body 21 to the outer surface, the wheel spindle stock 2 with a grinding wheel is inserted in each slit, and a moving means for sliding the wheel spindle stock 4 along the inner walls of the slits is built in. Slots 6, 8 are provided rather closer to the grinding wheel loading surface 5 of the wheel spindle stock 4, beams 10, 11 supported by fulcrums 7, 9 are formed on the wheel spindle stock 4, both beams are superposed one on the other to form a double beam structure on the wheel spindle stock 4, and the wheel spindle stock with the grinding wheel to which the elastic force is applied is used in the honing head to realize the flexible structure.
