PURPOSE:To make a joint stable against a vertical load and lateral pressure, by a method wherein a plurality of protruded lines are provided on the internal circumferential part of a rim, which are secured to a wheel disk with a bracket. CONSTITUTION:Protruded lines 13a and 13b are provided on the internal circumferential surface of a rim 12 in mutually unequal positions from the center of a widthward direction. The rim 12 is installed on a wheel disk 1 with a bracket 15. The bracket 15 is connected with the rim 12 over pressing down the protruded line 13 through force of tapered faces 5 and 16 by tightening a bolt and nut 24. A tread can be varied by changing a direction of the rim. Strength is improved against a load as a connection between the wheel disc 1 and the rim 12 is made into the protruded line. |
