ABSTRACT:
A direction setting device for rollers of a baby walker includes a pair of upper connectors, a pair of lower connectors rotatably connected to the upper connectors, and a control mechanism for permitting or preventing the relative rotation between the upper connectors and the lower connectors. The upper and lower connectors are utilized to connect the seat to the front rollers on the baby walker. Each of the upper connectors includes a spring biased key member. Each of the lower connectors includes a circumferential contacting surface capable of engagement with the key member and a key way in the contacting surface capable of engagement with the key member to prevent the relative rotation between the upper and lower connectors. The control mechanism is capable of urging the key members against the bias action of the springs so that the key members move away from the contacting surfaces of the lower connectors, and is capable of releasing the key members to abut on the contacting surfaces of the lower connectors. Upon the engagement of the key member in the key way, the rollers move unidirectionally.
