Abstract:
1. A roller burnishing apparatus comprising: 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; 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; and a relative-movement-direction defining mechanism which defines the relative movement direction in which the second member is movable relative to the first member, wherein the pressing-force detecting device includes a detecting portion disposed in series with the biasing device and between the first member and the second member.
