The steering dust seal is used for sealing a gap between a shaft hole of a column hole formed in an instrument panel and a steering shaft, and comprises an annular mounting part mounted on the inner circumferential surface of the shaft hole; an annular damper facing the steering shaft in a non-contact state; a bellows connecting the mounting portion and the damper; and a seal lip extending from the damper and contacting the steering shaft. The entire circumference of the lip of the seal lip is covered by a resin sliding portion having a friction coefficient that does not generate abnormal noise caused by stick-slip between the sliding portion and the rotating steering shaft.
转向防尘密封件,用于密封设置在仪表板上的柱孔的轴孔与转向轴之间的间隙,包括:环状的安装部,安装于轴孔的内周面;环状的缓冲器,以非接触状态面对转向轴;波纹管,连结安装部与缓冲器;以及密封唇,从缓冲器延伸并与转向轴接触。密封唇所具有的唇的整周被树脂制的滑动部覆盖,该滑动部具有在与旋转的转向轴之间不会产生由粘滑现象引起的异响的摩擦系数。
