PROBLEM TO BE SOLVED: To provide a bearing structure of a highly accurate roll used for a coating device. SOLUTION: Two angular bearings 18 and 20 are mounted on a rotary shaft 12 of the roll 10, and a first penetrating space 30 through which the rotary shaft 12 is passed is formed in a pair of bearings 28 and 29. The inside of the first penetrating space 30 is formed in a spherical shape, and a housing 32 with a spherical surface is fitted in the first penetrating space 30. A second cylindrical penetrating space 34 through which the rotary shaft 12 is passed is formed in the housing 32, and the angular bearings 18 and 20 are fitted in the second penetrating space 34.
