Claims

[Claims for Utility Model Registration] (1) A rotating shaft, an outer raceway formed directly on the outer peripheral surface of the rotating shaft, and an inner raceway formed on the inner peripheral surface,
The rotary shaft is rotatably supported by a bearing portion consisting of an outer ring fitted and fixed into a through hole of the bearing housing through which the rotating shaft passes, and a plurality of rolling elements installed between the outer raceway and the inner raceway. In addition, in the deflector attached to the outer circumferential surface of the rotating shaft, a circular deflector having an inner diameter approximately the same as the outer diameter of the rotating shaft is divided into a plurality of elements in the circumferential direction, and
A deflector for protecting a bearing portion, characterized in that the plurality of elements are attached to a rotating shaft and formed into a circular ring shape. (2) The circular deflector is divided into two elements in the circumferential direction, and the center angle of the inner peripheral edge of each element exceeds 180 degrees, and the central angle of the inner peripheral edge of the two elements is The deflector for protecting a bearing portion according to claim 1, wherein the ends thereof are formed in a shape that bites into each other.
