ABSTRACT:
A foldable stroller includes two locking devices for locking a frame body in an extended position, and a twist actuator mounted on and rotatable relative to a grip and having two cam paths disposed on an inner shell surface thereof. Two cam followers are interposed between the grip and the twist actuator, and have cam surfaces to confront and slidably engage the cam paths so as to move the cam followers along an axis when the twist actuator is rotated. Two keys are secured by the cam followers and extend radially and inwardly to be inserted into and slidable along two keyways formed in the grip. Two pulling cords respectively connect the keys with the locking devices to pull the locking devices so as to unlock the frame body when the cam followers are moved. A retaining member is disposed to prevent movement of the cam followers, and is manually operable to move radially.
