Abstract
A spinning reel spool is detachable from a spool shaft having a tapered surface and an engagement groove. The spool includes a spool unit, an engagement spring, a positioning projection, a lid member, an operation button, and an engagement hole. The spool unit includes a circular mounting space. The positioning projection determines the rotational position of the engagement spring. The operation button is mounted in the lid member and can pass over the engagement groove. The operation button includes a pair of tapered portions that are disposed with the spool shaft therebetween such that the gap between the pair of engagement portions is widened by movement of the operation button in the axial direction. The engagement hole controls the rotational position of the operation button.

A one-touch detachable fishing reel component for use in a fishing reel that has a shaft member having a tapered shaft surface formed on a tip of the shaft member, and an annular groove formed adjacent to the tapered shaft surface, said one-touch detachable fishing reel component comprising:
- a component unit having
- a pass through portion, the shaft member being adapted to extend therethrough, and
- a circular mounting space being formed in a front surface of said component unit, said circular mounting space being concentric with said pass through portion;
- an engagement spring made of a resilient wire member and being mounted in said mounting space, said engagement spring including
- a pair of engagement portions disposed opposite each other and adapted to engage with the annular groove, and
- a C-shaped connecting portion connecting one end of one of said engagement portions to one end of the other of said engagement portions;
- first positioning means for positioning said engagement spring within said circular mounting space, said first positioning means being disposed in said mounting space;
- a lid member configured to be fixedly coupled to said component unit, said lid member covering said mounting space and retaining said engagement spring therein;
- an operation member configured to be mounted on said lid member so as to be axially movable relative to said lid member and be able to pass over the annular groove, said operation member including
- a push operation portion being exposed to an exterior, and
- a pair of tapered portions projecting from said push operation portion in a direction opposite the exterior, tips of said pair of tapered portions being configured to be inserted between said engagement portions, said pair of tapered portions being adapted to be disposed in said mounting space with the shaft member interposed therebetween, a gap between said pair of engagement portions being configured to widen as said tapered portions are inserted between said engagement portions to release the engagement between the annular groove and said engagement spring;
- and
- second positioning means for controlling a rotational position of said operation member relative to said engagement spring.
A spinning reel, comprising:
- a reel unit having a handle;
- a rotor rotatably supported on a front portion of said reel unit;
- a spool disposed on a front portion of said rotor and reciprocally movable forward and backward along a spool shaft, said spool shaft having a tapered shaft surface formed on a tip of said spool shaft, and an annular groove formed adjacent to said tapered shaft surface, said spool having a spool unit detachably and non-rotatably mounted to said spool shaft, around an outer periphery of said spool unit fishing line being configured to be wound, said spool unit having
- a pass through portion, said spool shaft being designed to extend therethrough, and
- a circular mounting space being formed in a front surface of said component unit, said circular mounting space being concentric with said pass through portion;
- an engagement spring made of a resilient wire member and being mounted in said mounting space, said engagement spring including
- a pair of engagement portions disposed opposite each other and adapted to engage with said annular groove, and
- a C-shaped connecting portion connecting one end of one of said engagement portions to one end of the other of said engagement portions;
- first positioning means for positioning said engagement spring within said circular mounting space, said first positioning means being disposed in said mounting space;
- a lid member configured to be fixedly coupled to said component unit, said lid member covering said mounting space and retaining said engagement spring therein;
- an operation member configured to be mounted on said lid member so as to be axially movable relative to said lid member and be able to pass over said annular groove, said operation member including
- a push operation portion being exposed to an exterior, and
- a pair of tapered portions projecting from said push operation portion in a direction opposite the exterior, tips of said pair of tapered portions being configured to be inserted between said engagement portions, said pair of tapered portions being adapted to be disposed in said mounting space with said spool shaft interposed therebetween, a gap between said pair of engagement portions being configured to widen as said tapered portions are inserted between said engagement portions to release the engagement between said annular groove and said engagement spring;
- and
- second positioning means for controlling a rotational position of said operation member relative to said engagement spring.
