Abstract:

To achieve weight reduction of a pulley for a measuring conveyor around which a conveyance belt having, on an inner periphery, a ridge for preventing a meander is wound, and to allow dynamic balance of the pulley to be hardly lost.

A driven pulley 8 includes: a cylindrical roller body 12; a support shaft 13 inserted into the roller body; a pair of left and right bearings 14 fitted and attached internally into parts near both end parts of the roller body 12; and caps 15 fitted into and connected internally to both ends of the roller body 12. The almost whole range L1, of the roller body 12, on a center side in a pulley axis direction is set so as to be in a straight cylindrical shape having the same diameter, and ranges L2 from both end parts of the straight cylindrical range L1 to outer ends are formed in taper cylindrical shapes of which diameter becomes smaller toward outer end sides. At one part in the straight cylindrical range L1, a guide groove 11 is formed. On an inner periphery of the cylindrically formed pulley body 12, an annular protrusion 12a is formed, and on an outer peripheral part of the annular protrusion 12a, the guide groove 11 to be engaged with a ridge is annularly formed.
