A sheet conveyor includes: a chute which has openings spaced apart from each other in a first direction and guides a sheet; a drive shaft; drive rollers mounted on the drive shaft and each partly protruding from the chute through a corresponding one of the openings; driven rollers each urged and contactable with a corresponding one of the drive rollers; an intermediate bearing disposed at a first position located between adjacent two of the drive rollers; and a holder provided on the chute to hold the intermediate bearing located at the first position. The intermediate bearing is in contact with an outer circumferential surface of the drive shaft when located at a second position different from the first position. The intermediate bearing is slid from the second position to the first position in the first direction and held by the holder at the first position.
