Abstract
A transmission mechanism includes an output member and a worm wheel shaft configured to be connected to a power device to transmit a power of the power device to the output member. The worm wheel shaft and the output member are engaged with each other through a relative movement along an axial direction. An engagement between the worm wheel shaft and the output member limits a relative rotation between the worm wheel shaft and the output member.
