An input shaft structure for a transmission of a vehicle is provided to improve design freedom of the transmission by controlling two oil paths independently. A main path(3) is punched into the input shaft in a length direction of the input shaft. A pipe(5) is inserted into the main path. An external periphery of a portion of the pipe is spaced from an inner periphery of the main path. Both sides of the pipe are attached to the inner periphery of the main path. An inner coupling hole(7) is punched on the input shaft from both ends of the pipe, such that the inner coupling hole is connected to a space, where the outer periphery of the pipe is included. Outer coupling holes(9) are formed on the input shaft from both sides of the input shaft outside two ends of the pipe.
