摘要：: A fishing reel for winding and releasing a fishing line includes a tubular spool being configured to wind the fishing line onto an outer periphery thereof, a spool shaft made of metal, the spool shaft being attached to an inner periphery of the spool, and a Diamond Like Carbon (DLC) layer being formed on a surface layer side of the spool shaft.本發明之課題係在於可提升捲筒軸的耐磨耗性,且可減低軸承、小齒輪等的內周面與捲筒軸的外周面之摩擦抵抗。用以解決課題之手段為,捲筒(12)係藉由鋁合金所形成,在捲筒(12)的表層側,形成有進行了氧皮鋁處理之氧皮鋁層(81)。捲筒軸(16)係裝設於捲筒(12)的內周部,藉由不銹鋼合金所形成,在該捲筒軸(16)的表層側,形成有進行了PBID處理之DLC層(82)。12‧‧‧捲筒16‧‧‧捲筒軸81‧‧‧氧皮鋁層82‧‧‧DLC層(類鑽碳(Diamond Like Carbon)層)
