The object of the present invention is to maintain the anti-slip effect of the cover assembled on the reel of the fishing tackle and rotated by hand, and to suppress the deformation of the cover. The cover for the fishing tackle reel of the present invention is a cover 10 assembled to the reel body of the fishing tackle reel, and is provided with a bottomed cylindrical cover body 11 having a screw thread formed with the thread formed in the reel body The cylindrical portion 13 of the external thread 17 and the protrusion 16 formed on the outer surface of the cylindrical portion 13 and protruding radially outward； and the ring-shaped reinforcing member 21 formed with a recess 22 into which a part of the protrusion 16 of the cover body 11 is fitted So that at least a part of the protrusion 16 is exposed to the outer side in the radial direction, and the outer surface of the cover body 11 is fitted.本發明之課題在於保持裝配於釣魚具捲線器且以手轉動之蓋之防滑效果，並且抑制蓋之變形。本發明之釣具捲線器用之蓋係裝配於釣魚具捲線器之捲線器本體之蓋10，且具備：有底筒狀之蓋本體11，其具有形成有與形成於捲線器本體之螺紋螺合之外螺紋17之筒部13、及形成於筒部13之外側面且向徑向外側突出之突起16；及環狀之補強構件21，其形成有蓋本體11之突起16之一部分所嵌入之凹部22，使突起16之至少一部分露出於徑向外側，與蓋本體11之外側面嵌合。
