PROBLEM TO BE SOLVED: To provide carrying rollers for a disk drive which are arranged on the right and the left sides near an insertion port to carry a disk into the inside of the drive by clamping an outer circumference of the disk, eliminates slip by raising the contact pressure with the disk appropriately, realizes stable carrying-in/ejection, and improves durability by preventing the wear of the roller. SOLUTION: Spline grooves 24 are formed on the hole internal circumference of a roller 21 which is made of an elastic body such as rubber. Spline teeth 26 are provided on the outer circumference of a main body 22 and the roller 21 is fitted to the main body 22. The number of spline grooves 24 is made greater than the number of spline teeth 26, and gaps 28 are formed between the outer circumference of the main body and the roller hole internal circumference.
