PROBLEM TO BE SOLVED: To provide a driving force transmission mechanism for a motor-driven electric lock offering a simple construction and definite operation. SOLUTION: This is a thick-wall cylindrical body journaled to a base shaft 3 in a freely rotatable manner which comprises a drive body 4 formed with n lines (n: positive integer larger than 2) of shallow circular are grooves 5 on an outer peripheral surface, a roller holding wheel 6 which is journaled in a rotatable manner through a friction linkage to the base shaft in connection to the drive body 4 with n-number of V-shaped operation notches 7 opening outwardly to an outer peripheral edge, n-number of rollers 12 with one end portion linked to the circular arc groove and other end portion linked to an operation notch of the roller holding wheel and these are mutually jointed together, a cup shape circumscribing to m-number (m: positive integral number larger than 1)×n lines of shallow recess lines 11 are formed around the center shaft line, a follower body 8 journaled in a freely rotating manner by the base shaft 3 is also provided, the drive body 4 is coupled to a micro motor through a speed reduction gear train and the follower body is jointed to a dead cam 14.
