A stepless unidirectional rotation device includes a housing, a connecting component, a lower roller bearing, turntable assembly, a switching mechanism, a suppressing component and an upper roller bearing. The housing has a receiving room. The connecting component includes a shaft, and one end of the shaft extends out of the receiving room. The lower roller bearing is disposed in the receiving room and rolling contacts with the housing. The turntable assembly includes a rotating disc and a washer. The rotating disc includes a flat surface and an oblique surface. The switching mechanism is connected with the rotating disc. The suppressing component is disposed in the receiving room and is set around the shaft. The upper roller bearing is sandwiched between the washer and the suppressing component and rolling contacts with the suppressing component. Thus, the self-locking or loose problem can be avoided.
