ABSTRACT:
A cover faces an end portion of a ball head cup attached to an end of a head pipe and is fitted on a fork stem. A rolling ball group is interposed between the ball head cup and the cover. A top cone is put on the rolling ball group from the cover side. The cover is formed of rubber or an elastic synthetic resin. The outer periphery of the cover is configured to be in contact with the inner periphery of the ball head cup. A cone ring inserted in the top cone and having a slit in its side wall is attached in the cover. Thus, the cover prevents the invasion of rainwater etc. through the slit of the cone ring.
