IPC: B62D1/16
Filed: 1985-07-04
Abstract: PURPOSE:To prevent an oil seal from being damaged and deteriorated by configurating a device in such a way that muddy water which penetrates into a housing supporting a steering shaft, through a gap between the housing and a cap, is allowed to flow down along a circular groove while making use of the inclination of an end surface. CONSTITUTION:A circular groove 15 is formed on the end surface 3a of a housing 3 surrounding a steering shaft 2. As the housing 3 is titled, the end surface 3a is also tilted by the specified angle, therefore, the circular groove 15 is tilted by the specified angle from the level line. Accordingly, a water drop which penetrates inside to the direction as shown by an arrow head B through a gap rho between a cap 5 and the housing 3 while a vehicle is running, drops into the circular groove 15, then flows down to the lowermost point 15a. If the quantity of muddy water having penetrated is increased, it overflows from the lowermost point 15a, then flows out along the end surface 3a and the side surface 3b as shown by an arrow head C, and then drops down on the ground. Resultantly, this configuration is capable of preventing muddy water from standing in an oil seal 4.
