PURPOSE: Structure for engaging a spline is provided to improve durability by preventing wear and to improve power transmitting efficiency. CONSTITUTION: Spline connecting structure comprises a main shaft(2) rotating by connected to a driving force generator; an auxiliary shaft(4) transferring driving force by being engaged with the main shaft; a spline rod unit(8) formed on an outer portion of the main shaft; gear tooth(6) arranged on the spline rod unit; a spline inserting unit(10) installed on an inner circumference of the main shaft to insert the spline rod unit; a gear groove(12) formed on the spline inserting unit; and a lubricating oil supplying unit supplying lubricating oil into a frictional face between the gear tooth and the gear groove. The lubricating oil supplying unit is formed between the spline rod unit and the spline inserting unit. Thereby, the spline connecting structure improves durability by preventing a wear.
