A rear section short girder and a front section short girder of a tricycle frame are folded from middle rises; through a hinge, a front fork handlebar is exerted to rotate to approach the hinged part of the front section short girder connected with the rear section short girder; a seat cushion bracket is exerted to rotate through a hinge so that a seat cushion approaches a hinge part of the rear section short girder connected with the front section short girder; therefore, a handle and the seat cushion of the frame approach each other and a front wheel approaches rear wheels of the frame to enter between the two rear wheels so that the whole tricycle frame is folded.
