Abstract
A writing instrument such as a mechanical pencil is provided with a brush for eliminating static electricity. The instrument is composed of a barrel and a barrel cap attached to the barrel. A base portion of the brush is fixedly received in a cylindrical protector arranged within the barrel cap. A writing element operating mechanism is arranged to operably hold a writing element such as a lead so that the writing element can be selectively extended from and retracted into the barrel. A brush operating mechanism is also arranged to hold the protector movably along a central axis of the barrel cap so that the brush can be selectively extended from and retracted into the barrel cap. A cylindrical member may preferably be fixedly secured in a rear end of the barrel cap to guide the brush. One of the operating mechanisms can be actuated by causing one of the barrel and the barrel cap to move relative to the other in an axial direction, and the other operating mechanism can be actuated by causing one of the barrel and the barrel cap to turn relative to the other.
