PURPOSE:To simplify manufacture of wheels of a variety of designs and shapes by assembling a joining part of a disc and each of the front and the rear rims located its outer circumferential part in a body with tightening a common bolt through a hardening type adhesive. CONSTITUTION:An aluminum alloy disc 1 is so constituted that an axle hole 1c is formed on the central part and a projecting piece 1a on the circumferential end, and that a hole 1b for fitting of a bolt is provided at an appropriate position on the projecting piece 1a. And each of the rear and the front rims 2 and 3 installed on this disc 1 are formed in the ringed shape with the cross section of approximately the letter 'S' respectively and so constituted that projecting parts 2a and 3a for stopping the tire are provided on one end and joining parts 2b and 3b on the other end, and holes 2c and 3c for inserting of bolts are provided on each of the joining parts 3a and 3b. And for the assembly of a wheel 6, first, an epoxy resin type adhesive 5 is applied to the contact part of the joining parts 2b and 3b and the projecting piece 1a, a bolt 4 is inserted into each of the holes 1b, 2c and 3c and this is tightened to finish the assembly.
