<P>PROBLEM TO BE SOLVED: To prevent the come-off of a bearing for an eccentric mechanism of a four-bar linkage type continuously variable transmission. <P>SOLUTION: The continuously variable transmission 1 comprises a plurality of the eccentric mechanisms 4 each having a fixed disk 5 and an oscillating disk 6. A receiving hole 6a for receiving an input shaft 2 and the fixed disk 5 is fixed at the oscillating disk 6. The receiving disk 6a is formed of a small-diameter hole 6c positioned in the axial center and a large-diameter hole 6d which is formed so as to axially surround the small-diameter hole 6c, and a step 6e formed between the small-diameter hole 6c and the large-diameter hole 6d. The bearing 21 for the eccentric mechanism is arranged between the fixed disk 5 and a large-diameter hole 6d. The bearing 21 comprises a retainer 23 for holding a plurality of rolling bodies 22 and an outer ring 24. A hanging part 24a hanging between the step 6a and the fixed disk 5 is formed at the outer ring 24. <P>COPYRIGHT: (C)2013,JPO&INPIT |
