A lower body member is secured to the upper end of the post and has the lower ends of front and rear parallel arms pivotally secured thereto. An angular upper body member is pivotally secured to the upper ends of the front and rear parallel arms. A pin is pivotally secured at its upper end to the front parallel arm and has its lower end in engagement with a suspension guide which is slidably received in the upper end of the post. A spring or elastomer members are positioned in the post with the upper end of the spring or the elastomers being received by the suspension guide.
