PURPOSE: Provided is a control device for controlling a height of a supporter such as cup holder and coat hanger, corresponding to a demand of a user, which is conveniently used by children. CONSTITUTION: A height of a supporter comprises a guide rail(200), a movable member(100) and a supporter(300). The guide rail is formed with many locking recesses(210) at a certain interval. The movable member is made of a resilient member(400). The movable member is formed with a hole(110) which is screwed with a bolt(600) for controlling an amount of resiliency of the resilient member such as a spring. When a ball bearing is inserted into the locking recess, motion of the movable member is not transferred to an upper portion of the guide rail by the elastic force of the resilient member. |
