In order to securely fix the guide member 92 to the bearing member 91, the inner peripheral surface of the guide member 92 and the outer peripheral surface of the outer ring 912 may be bonded with an adhesive or the like. In this case, the bearing member 91 may be fitted to the guide member 92 or may not be fitted.

Modification 4
The guide member 92 may have a surface treatment layer by performing a surface treatment on at least the guide surface 921, and guides a surface treatment layer such as DLC (diamond-like carbon) by, for example, a CVD method or a PVD method. The member 92 can be formed on at least the guide surface 921. In addition, IP (Ion Plating) may be applied to at least the guide surface 921 of the guide member 92. Before the guide member 92 is fixed to the bearing member 91, it is preferable to perform various surface treatments on the guide member 92. As a result, only the guide member 92 can be subjected to the surface treatment without subjecting the bearing member 91 to the surface treatment. As a result, it is possible to prevent the smoothness of rotation of the bearing member 91 from being impaired.

Modification 5
In the above embodiment, the outer ring 912 of the bearing member 91 and the guide member 92 are formed of the same metal or alloy with the same ionization tendency. However, if the ionization tendency is the same to the extent that no electrolytic corrosion occurs, the ionization tendency is completely the same. Need not be.

Modification 6
FIG. 9 is a cross-sectional view of a line roller according to Modification 6. In the above embodiment, the first and second seal members 94a and 94b have inner end portions in contact with the first or second restricting members 93a and 93b. However, the present invention is not limited to this.

  For example, as shown in FIG. 9, the first seal member 94a can be configured not to contact the first restricting member 93a. Specifically, the inner peripheral side end portion 942a of the first seal member 94a faces the outer peripheral surface of the first restricting member 93a with a space therebetween. The distance between the inner peripheral side end portion 942a of the first seal member 94a and the outer peripheral surface of the first restricting member 93a is preferably about 0.05 mm to 0.3 mm, and preferably about 0.1 mm to 0.2 mm. More preferably. At least one of the inner peripheral side end portion 942a of the first seal member 94a and the outer peripheral surface of the first restricting member 93a has water repellency.

  The 2nd seal member 94b can be set as the structure which is not in contact with the 2nd control member 93b. Specifically, the inner peripheral side end portion 942b of the second seal member 94b faces the outer peripheral surface of the second restricting member 93b with a space therebetween. The distance between the inner peripheral side end portion 942b of the second seal member 94b and the outer peripheral surface of the second restricting member 93b is preferably about 0.05 mm to 0.3 mm, and preferably about 0.1 mm to 0.2 mm. More preferably.

  At least one of the inner peripheral side end portion 942b of the second seal member 94b and the outer peripheral surface of the second restricting member 93b has water repellency. In this modification, the outer peripheral surface of the first restricting member 93a and the outer peripheral surface of the second restricting member 93b have water repellency in consideration of aging, the influence of the external environment, ease of water repellent treatment, and the like. Have.
