ABSTRACT:
A stroller includes a wheel frame and a handle frame. The handle frame includes a grip member and two swing rods. The swing rods are spaced apart from each other in a left-to-right direction, and are connected pivotally to the wheel frame. The grip member has two extension rod portions that are connected respectively and pivotally to the swing rods so as to allow the grip member to be folded on the swing rods. Two slide sleeves are sleeved respectively and movably on the extension rod portions. Two rod-retaining seats are disposed respectively on the slide sleeves, and engage respectively and automatically retaining grooves in the swing rods so as to prevent the grip member from pivoting upwardly away from the swing rods when the grip member is folded on the swing rods.
