A dual-ratchet wheel transmission apparatus includes: a drive wheel set, having a first drive wheel and a second drive wheel coaxially integrated with a drive shaft; a driven wheel set, being coaxially set with a driven shaft in which the driven shaft is connected to an output for transmission, the driven wheel set including: a first driven wheel being centrally integrated with a unidirectional ratchet wheel, in which the first driven wheel engages with the first drive wheel for transmission, a second driven wheel being centrally integrated with another unidirectional ratchet wheel, in which the second driven wheel is connected to the second drive wheel via a transmission element. By the aforementioned configuration, whether the drive wheel set rotates forward or backward, the transmission set rotates in only one direction.
