Abstract
There is disclosed a roller burnishing apparatus including a first member moved relative to an object to be burnished, a second member movable relative to the first member in a relative movement direction, a burnishing roller held by the second member such that the burnishing roller is rotatable, a biasing device which biases with a biasing force the second member relative to the first member in one of two opposite directions along the relative movement direction, and a pressing-force detecting device that detects a pressing force with which the burnishing roller is pressed against the object and which is based on the biasing force of the biasing device.
