ABSTRACT:
A transmission ratio variable mechanism (100) varies a transmission ratio between a steering amount of a steering wheel (2) and a turning amount of wheels (7). The transmission ratio variable mechanism (100) includes an input shaft (3) transmitted with a rotational force of the steering wheel (2), a housing (102, 103) unitarily rotating with the input shaft (3), an output shaft (4) connected to wheels side, a motor (160) fixed in the housing for transmitting the rotation to the output shaft (4) via a speed reduction device (150), and a reverse input blocking device (180) for always transmitting a rotational output from the motor (160) to the output shaft (4) and for always blocking a rotational input from the output shaft (4) to the motor (160).
