Abstract
A collapsible scooter has a frame plate secured on a head tube of the scooter, a strut having a lower end thereof pivotally connected to a foot board of the scooter and an upper end thereof pivotally connected to the frame plate. Opposite sides of the frame plate are symmetrically defined with two pivot slots, the upper end of the strut is pivotally connected with the frame plate and movable along the pivot slots between an upper position in which the scooter is fully collapsed and a lower position in which the head tube is uprightly extended. A retaining device is particularly provided in the scooter to prohibit the head tube from any inadvertent movement relative to the foot board, even when the head tube is subjected to excessive stress during riding on a rough road.
