To provide a honing device in which a predetermined surface roughness is obtained and a raising of a work cost and an equipment cost is inhibited by inhibiting a generation of a working pressure between honing sticks having a different grading caused by a difference of abrasion amount of individual honing sticks in the case where different kinds of the honing sticks are attached.

The honing device is provided with a rotation cylinder 2; a honing head 3 having a cylindrical shape, provided with honing sticks 31A, 31B radially movable on an outer periphery surface and rotating with the rotation cylinder 2; and a stick driving mechanism 4 for radially moving the sticks 31A, 31B. A hydraulic chamber 47 converting stick driving force transmitted to the stick driving mechanism 4 to hydraulic pressure and transmitting the hydraulic pressure to the respective sticks 31A, 31B is provided on the stick driving mechanism 4.
