Abstract

A disclosure relates to a gear two-way clutching mechanism that is acted between the power output and the loading and mainly comprising a power source, a loading, a clutching unit and a deceleration unit. When the first output gear of the loading unit is driven by the power source to rotate to a predetermined position, the teeth missing portion is tangential with and corresponds to the buffer gear, or the wheel teeth portion meshes the buffer gear. The clutching unit connected between the power source, and the loading can perform clutch without working and enables the loading end to freely rotate, or the clutching unit can perform mesh working so that power of the power source is directly outputted to the loading end. With the deceleration unit connected to rear section and/or front section of the clutching unit, speed reduction ratio of the transmission chain connected between the power source and the loading can change to achieve effect of enhancing or changing output torque.
