A device for starting an engine of a hybrid vehicle is disclosed. The device for starting an engine of a hybrid vehicle according to an embodiment of the present invention includes: an input shaft connected to a hybrid starter generator; an output shaft connected to a crankshaft of an engine; a planetary gear set having three rotary elements and disposed between the input shaft and the output shaft so as to convert rotational torque; and a plurality of one-way clutches selectively connecting two of the three rotary elements of the planetary gear set and selectively connecting the other rotary element to a transmission housing. Accordingly, the present invention is able to allow a big gear ratio to secure startability at the time of starting an engine and free a small gear ratio from a limit of the maximum number of rotations.
