Abstract
A stationary nonequilibrium state for the Feynman ratchet is realized in a Langevin simulation with a stochastic boundary condition. We calculate the temporal fluctuation of the total entropy production and show that the "fluctuation-theorem" is valid for this stochastic system. An Einstein relation between the diffusion constant and the response coefficient is numerically verified.
