A ratchet handle includes a detent. A front part of the detent has a first meshing portion and a second meshing portion to mesh with a ratchet gear. An accommodation recess is provided between the first meshing portion and the second meshing portion. An auxiliary member is provided in the accommodation recess. The auxiliary member has a curved surface corresponding to an outer contour of the ratchet gear. The ratchet handle further includes an operating device. The operating device is operated to turn the detent so as to control the first meshing portion or the second meshing portion to mesh with the ratchet gear. The detent of the present invention is turned with less noise and moved stably.
