PROBLEM TO BE SOLVED: To easily ensure a set bonding strength in a joined wood part. SOLUTION: This wheel has a ring part core 12 and a soft cover part 14 covering the same, wherein the part 14 is formed by low pressure ejection formation and the part 14 is covered with a jointed wood part 16 made of upper and lower split wood bodies 16A, 16b. A parting line(PL) of the part 14 is deviated in position by an amount L from a joined surface 16a of the joined wood part 16 in the upper and lower direction. With such a constitution, biting-in of remaining bur 20 to the joining surface 16a is reduced, and thereby a bonding strength can be easily ensured in the joined wood part.
