PROBLEM TO BE SOLVED: To provide a sash roller capable of changing a position in the axial direction of a rotating shaft of a wheel. SOLUTION: This sash roller has: an outer frame 2; a moving body 5 which is arranged in the outer frame 2 so as to be horizontally movable and in which a recess 13, recessed forward, is formed in a rear surface; an inner frame 3 which is arranged in the outer frame 2 and whose back end is mounted on the moving body 5 in a vertically oscillatable manner so that the inner frame 3 can be horizontally moved with the moving body 5; and the wheel 4 which is rotatably supported on the inner frame 3. A rack 14 having a plurality of teeth 14a is formed in an under surface of the recess 13. A pinion 17 having teeth 17a, which are engaged with the teeth 14a, is arranged in the recess 13. A backward protruding part 21 is provided in a rear surface of the pinion 17. A plurality of teeth 21a are formed on a peripheral surface of the protruding part 21. A spring 18 for urging the pinion 17 backward is arranged between the pinion 17 and a bottom surface of the recess 13. A pinion fixing plate 19 is arranged between a rear surface part 2d and the moving body 5. A through-hole 24, into which the protruding part 21 is to be fitted, is formed in the plate 19. A plurality of teeth 24a for being engaged with the teeth 21a are formed in an inner peripheral surface of the through-hole 24. COPYRIGHT: (C)2004,JPO
