PROBLEM TO BE SOLVED: To provide a line roller for a spinning reel line roller, which prevents water from entering the bearing from between a support member for radially supporting the bearing and a collar for fixing the axial position of the bearing. A line roller (3) has a cylindrical guide member (6) having a guide surface for guiding a fishing line on its outer circumference, and a first bearing (11) and a second bearing (12) rotatably supporting an inner peripheral surface of the guide member (6). A support shaft 24 that radially supports the inner peripheral surfaces of the first bearing 11 and the second bearing 12, and a first collar that abuts the end surfaces of the first bearing 11 and the second bearing 12 to fix the axial position. 4 and the second collar 5, the first groove 25 and the first groove 25 formed on the joint surface between the first collar 4 and the second collar 5 and the support shaft 24 and continuous over the entire circumference around the rotation axis of the guide member 6. The O-rings 13 and 14 are arranged in the groove 26 of No. 2, respectively.
