PURPOSE: A motor driven power steering device is provided to improve productivity by improving the power transmission structure between a worm shaft and a motor driving shaft and reducing the number of components and an assembly process. CONSTITUTION: A motor driven power steering device (1) comprises a worm wheel gear (22), a first connector (40), a second connector (60), and a coupling part (70). The worm wheel gear is fixed on the outside of a steering shaft (20). The first connector is connected to a worm wheel shaft (30) which is interlocked with the worm wheel gear. The second connector is connected to a motor drive shaft (50) and is installed to face the first connector. The coupling part is installed along the outer circumference of the first and second connectors. The coupling part transmits power by being connected to the first and second connectors.
