    • A weight for adjusting balance of a rotating body obtained by adding and mixing one or two or more sorts of solid spherical powders selected from silicated glass, boro-silicated glass and phosphate glass to and with ultraviolet curing resin. The weight has improved specific gravity which is capable of sufficiently hardening even the inner part thereof without remaining an unhardened part in a short time only by being exposed to ultraviolet rays and suitable for a rotating body such as a rotor in a motor of a brushless outer rotor type or a brush motor and a polygon mirror for use in a laser printer because the powder particles thereof can be intimately bonded with one another through the adhesive resin.
