PURPOSE: Reinforcing structure of a side door for a vehicle is provided to improve the rigidity of a side door frame by dividing an inner panel of the side door into an upper part and a lower part, and by integrally forming a lock reinforcing member with a sash reinforcing member. CONSTITUTION: An inner panel is connected to an outer panel, and a glass is inserted between the inner panel and the outer panel. An upper channel(24) is mounted in a side door of a vehicle to guide the glass. The inner panel is divided into an upper inner panel(21) and a lower inner panel(22). Lock and sash reinforcing members(25) are integrally formed from the handle of the lower inner panel to the sash of the upper inner panel. The lower part of the upper channel is fastened in the lower inner panel by a channel bracket(26). The rigidity of the side door frame is improved with integrally forming lock and sash reinforcing members.
