ABSTRACT:
This invention relates to a controlling structure for a handle and castors of a stroller and in particular to one utilizing a driven seat to activate a movable member which in turn pulls two strings so as to change the front castors from a freely rotatable state to a fixed-position state and the rear castors from a fixed-position state to a freely rotatable state when the handle is pushed to the other side, thereby enabling a user to control the stroller easily even when he pushes the handle to the other side so as to change the travelling direction.
