PROBLEM TO BE SOLVED: To provide a spinning reel for fishing which is easy to adjust braking of a spool when a fishing line is sent out and suppresses the change of a braking feeling when being slipped due to moisture or the like and pulling a fish.SOLUTION: The spinning reel for fishing includes a spool 7 having a fishing line-winding drum part 7a for winding the fishing line and a skirt part 7c, and a drag mechanism 15 for imparting the braking force to the rotation of the spool. In the skirt part 7c, a plurality of narrow through-holes 20 linearly extending in the direction along a spool shaft 6 are formed substantially uniformly throughout the circumferential direction. The through-holes 20 are formed such that a component of the direction along the spool shaft 6 is larger than a component of the circumferential direction and an interval of the mutually adjacent through-holes is 1.0-10 mm.COPYRIGHT: (C)2012,JPO&INPIT【課題】釣糸が繰り出された際のスプールの制動調整がし易いと共に、水分等による滑りや魚の引きとのやり取り中において、制動感の変化を抑えた魚釣用スピニングリールを提供する。【解決手段】魚釣用スピニングリールは、釣糸が巻回される釣糸巻回胴部7aとスカート部7cを有するスプール7と、スプールの回転に制動力を付与するドラグ機構15とを有し、スカート部7cに、スプール軸6に沿う方向に直線状に延びる細幅の貫通孔20を、周方向に亘って略均一に複数本形成する。そして、貫通孔20は、スプール軸6に沿う方向の成分が周方向成分より大きく、かつ隣接する貫通孔同士の間隔が1.0~10mmで形成されている。【選択図】図1
