摘要 |
<p>The invention provides a telescopic shaft including a male shaft and a female shaft which are so fitted as to be capable of a sliding motion but incapable of a rotation and in which an external periphery of the male shaft and an internal periphery of the female shaft are in contact with each other to transmit a torque in case of rotation, wherein a grease, containing a base oil having a dynamic viscosity of from 10 to 210 mm 2 /s at 25°C and an extreme pressure additive, is sealed in a gap between the external periphery of the male shaft and the internal periphery of the female shaft. The construction enables a satisfactory torque transmission without detrimentally influencing the feeling of steering.</p> |
