A device for varying wheel spoke size is provided to improve appearance of a wheel by containing a spoke varying member inside a spoke, and to reduce wheel noise and air resistance by making the spoke varying member to be bounced out from the spoke so as to increase spoke size at the time of high speed driving of a vehicle. A device for varying wheel spoke size comprises a mounting groove and a spoke varying member. The mounting groove provided with an opening part(11) in one part is formed inside a spoke(1) of a wheel(2). The spoke varying member is contained inside the mounting groove, bounces outside through the opening part of the mounting groove by inertia force in case of high speed driving of a vehicle, and increases size of the spoke.
