The present invention relates to a rotary sensor assembly and a rear wheel steering system including the same. According to one embodiment of the present invention, a rotary sensor assembly includes: a rotary sensor subassembly configured to sense a stroke of a driving shaft configured to receive rotating power to move linearly; a sensing guide configured to be moved by receiving a moving force when the driving shaft moves such that the rotary sensor subassembly senses movement of the driving shaft; and fasteners which couple the sensing guide to the driving shaft, wherein the rotary sensor subassembly senses movement of the sensing guide to sense the stroke of the driving shaft when the driving shaft moves.

The present invention relates to a power transmission device of an electric power steering apparatus. The power transmission device includes: a driving shaft of a motor having an accommodation part formed at a rotation center thereof; a coupling member inserted into the accommodation part and having an axial through-hole formed therethrough; and a gear shaft including a coupling part formed on one side thereof to be coupled to the axial through-hole, and a gear part formed on the other side thereof. According to the present invention as described above, in a power transmission device of an electric power steering apparatus, it is possible to reduce rattle noise generated as backlash increases due to wearing-out of a gear or generated due to impact transmitted from a road surface through a vehicle wheel and a steering shaft while improving a driver's steering feeling by reducing a locking feeling and a rotational resistance between a driving shaft of a motor and a gear shaft.

Disclosed is a planetary gear reducer for a vehicular steering apparatus. The planetary gear reducer includes: a sun gear, to which a steering shaft is joined; a planetary gear circumscribing the sun gear; a carrier, to which a rotary shaft of the planetary gear is joined; a ring gear, in which the planetary gear is inscribed; and backlash compensation members. The backlash compensation members are coupled to one or more of the sun gear, the planetary gear, and the ring gear such that the backlash compensation members are rotated in a state where they are in close contact with each other.

Disclosed is an electric power steering apparatus for a vehicle. The electric power steering apparatus for a vehicle has a structure in which a motor shaft, an input shaft, a pinion shaft, and the like are coaxially disposed to improve a structure of a conventional art in which an electric motor is essentially exposed, so as to prevent interference with other structures, thereby forming a layout of the steering apparatus to be compact.
