PROBLEM TO BE SOLVED: To remove deposits deposited in a sprocket cover interior by a simple configuration. SOLUTION: One part of a sprocket 46 is covered by a sprocket cover 90. The sprocket cover 90 is composed of an upper cover 91, a lower cover 92, and a cradle 93. An outlet 93a discharging the deposits from a side of the sprocket 46 is formed in the cradle 93. Inclined planes 93b, 93c for guiding the deposits to the outlet 93a by gravity are formed in a bottom of the cradle 93. An excitation part 96 and a heating part 97 are connected to the cradle 93. The excitation part 96 applies vibration to the cradle 93 to facilitate slipping of the deposits. The heating part 97 heats the inclined planes 93b, 93c to facilitate slipping of the deposits. A suction tube 99 of an air cleaner 98 is connected to the outlet 93a, and the deposits are recovered by suction. COPYRIGHT: (C)2010,JPO&INPIT |
