A harmonic reducer with clutch function includes a circular spline, a mounting base, a flexspline and a wave generator. When a power source drives the wave generator to rotate in a first direction, a one-way clutch engages to lock the mounting base so as to deform the flexspline and hence rotate the circular spline in the first direction. When an external force is applied to the output shaft in the first direction, the mounting base is driven by the flexspline so the one-way clutch disposed thereon is disengaged by a force in a second direction. At this moment, the rotation speed of the wave generator is equal to zero relative to the flexspline, so the wave generator can be driven by the circular spline to rotate along with the flexspline, and the central axel of the wave generator can be driven to rotate as well.
