The wire roller of the spinning wheel reel of the present invention prevents water from penetrating into the bearing from the support member that supports the bearing in the radial direction and the collar that fixes the axial position of the bearing.The wire roller 3 of the present invention is provided with: a cylindrical guide member 6 having a guide surface for guiding the fishing line on the outer periphery； a first bearing 11 and a second bearing 12, which connect the inner peripheral surface of the guide member 6 Supported in a rotatable manner； supporting shaft 24, which supports the inner circumferential surfaces of the first bearing 11 and the second bearing 12 in the radial direction； the first collar 4 and the second collar 5, which abut against the first bearing 11 and the end surface of the second bearing 12 to fix the position in the axial direction； and O-rings 13, 14, which are interposed on the first collar 4 and the second shaft throughout the entire circumference of the rotation axis of the guide member 6 The joint surface of the ring 5 and the supporting shaft 24. The O-rings 13, 14 are respectively arranged on the first groove 25 and the second groove formed on the joint surface of the support shaft 24 with the first collar 4 and the second collar 5, and are continuous around the entire circumference of the rotating shaft Slot 26.本發明之紡車式捲線器之導線輥防止水自於徑向支持軸承之支持構件、與固定軸承之軸向位置之軸環之間滲入軸承。本發明之導線輥3具備：圓筒狀之導引構件6，其於外周具有導引釣線之導向面；第1軸承11及第2軸承12，其等將導引構件6之內周面以能夠旋轉之方式支持；支持軸24，其於徑向支持第1軸承11及第2軸承12之內周面；第1軸環4及第2軸環5，其等抵接於第1軸承11及第2軸承12之端面而將軸向之位置固定；及O形環13、14，其等遍及繞著導引構件6之旋轉軸之全周而介存於第1軸環4及第2軸環5與支持軸24之接合面。O形環13、14分別配置於形成於支持軸24之與第1軸環4及第2軸環5之接合面、且遍及繞著旋轉軸之全周而連續之第1槽25及第2槽26。
