PURPOSE: A liquid pressure transfer printing method of a steering wheel rim for an automobile is provided which reduces a plurality of succeeding processes, thereby remarkably improves productivity by replacing a mask member used in printing certain patterns with a polyvinyl alcohol layer itself of a transfer printing film used in transfer printing. CONSTITUTION: In a liquid pressure transfer printing method of a steering wheel rim in which certain patterns are printed on the surface of the steering wheel rim by liquid pressure transfer printing the halved surfaces of the steering wheel rim on a transfer printing film in which a pattern layer is formed on a polyvinyl alcohol layer by halving the surface of a steering wheel rim, the liquid pressure transfer printing method of the steering wheel rim for an automobile comprises a first transfer printing process of stably descending the steering wheel rim by a boundary line of the preferential area to be transfer printed within a certain period of time with a separate mask member not being adhered to the residual half part in a length direction except for a preferential area to be transfer printed of the steering wheel rim after floating the transfer printing film(4) on the surface of a liquid solution; a semi-drying process of drying the polyvinyl alcohol layer(4b) coated on the half surface in a length direction of the steering wheel rim(2) through the first transfer printing process to a certain drying ratio for a certain period of time; a second transfer printing process of stably descending the steering wheel rim by a boundary line or above of the residual half area to be transfer printed in a length direction after reversely turning the steering wheel rim(2) when the polyvinyl alcohol layer(4b) is dried on the outer side of the first transfer printed surface through the semi-drying process in the gel state; and an all surface washing process of simultaneously washing the polyvinyl alcohol layer(4b) of the outer side by dipping the steering wheel rim(2) on all over the surface of which transfer printing is completed into the liquid solution for a certain period of time.
