A dust cover for a steering shaft attached to an vehicle body in such a way as to be in contact with the steering shaft to provide protection against dust and muddy water is provided with a cylindrical contact member that is to be in sliding contact with the steering shaft while the steering shaft is rotating and a cylindrical reinforcement member for reinforcing the cylindrical contact member provided radially outside the cylindrical contact member. A low friction material is attached, by coating or baking, to such a portion of the cylindrical contact member that is in contact with the steering shaft, or alternatively, the cylindrical contact member itself is made of a low friction member.
摘要:
A PZT fiber is formed by using a titanium wire or a heat-resistant metal wire made of platinum or the like, as a core wire, and overlaying PZT crystals on a surface of the wire. A smart board utilizing the PZT fiber is formed by embedding the PZT fiber into a conductive composite material layer made of carbon fiber reinforced plastic or the like. An actuator utilizing the smart board is constituted by applying a voltage between the PZT fiber and the conductive composite layer of the smart board.
