<P>PROBLEM TO BE SOLVED: To provide a conveying device structured to easily supply a treatment agent, and shaft units for use in the conveying device. <P>SOLUTION: Each of bearing holders 220 of the shaft units 11A (and 11B, 11C, 11D) has a flange part 221 around the axial direction, and the flange part 221 is provided to be exposed to the outside. Grease injection ports 224, 225, 226 are formed in a plane part 223 which is a part of the flange part 221, and the shaft units 11A (and 11B, 11C, 11D) connect a driving unit 50 and an arm part to expose these grease injection ports. An operator can thereby inject grease easily from the injection ports 224, 225, 226 without removing the arm part from the shaft unit 11A. <P>COPYRIGHT: (C)2011,JPO&INPIT |
