Abstract
Nut that screws together with pinion gear, and bearing that is arranged on the inner circumferential side of the nut, are provided on the front of a spinning-reel rotor. Pressing member is mounted on the front faces of the nut and bearing, such that it abuts on outer race of bearing. Pressing member is installed so as to be rotatable with respect to spool shaft, which is a rod element. Pressing member is water-repellency treated over all its surfaces, including the face that forms a clearance with spool shaft. The present invention prevents invasion of water droplets into rotatory-component clearances in a water-sealing component assembly composed of a relatively rotatable plurality of components, while sustaining rotational efficiency of the rotatory components.
Claims21
A water-sealing component assembly, comprising:
- a first component that is rotatable around a rotational axis;
- a second component arranged adjacent said first component such that a micro clearance is defined between clearance-defining surfaces of said first and second components, said first component being rotatable relative to said second component via a bearing that has an inner race and an outer race and is disposed adjoining at least one of said first and second components in a direction of the rotational axis, said micro clearance being smaller than a gap between said inner and outer races of said bearing;
- sealing means for preventing water from invading the gap between said inner and outer races of said bearing solely by water repellency of a water-repelling film layer provided on at least said clearance-defining surface of said first component, said sealing means having said micro clearance and said water-repelling film layer.
The water-sealing component assembly, comprising:
- a first component;
- a second component arranged adjacent said first component such that a clearance is defined between clearance-defining surfaces of said first and second components, said first component being rotatable relative to said second component;
- a water-repelling film layer provided on at least one of said clearance-defining surfaces of said first and said second components that define said clearance;
- a bearing having an inner race and an outer race;
- and
- a rod member attached to said inner race of said bearing,
- said first component having a pressing member that is attached to said outer race of said bearing,
- said second component having a cylindrical member that is fitted to said rod member,
- said cylindrical member having a plurality of projecting portions.

A fishing reel attachable to a fishing rod, said fishing reel comprising:
- a reel body to be attached to the fishing rod;
- a first component that is rotatable around a rotational axis;
- a second component unrotatable relative to said reel body, said second component being arranged adjacent said first component such that a micro clearance is defined clearance-defining surfaces of said first and second components, said first component being rotatable relative to said second component via a bearing that has an inner race and an outer race and is disposed adjoining at least one of said first and second components in a direction of the rotational axis, said micro clearance being smaller than a gap between said inner and outer races of said bearing;
- and
- sealing means for preventing water from invading the gap between said inner and outer races of said bearing solely by water repellency of a water-repelling film layer provided on at least said clearance-defining surface of said first component, said sealing means having said micro clearance and said water-repelling film layer.

- and
- sealing means for preventing water from invading the gap between said inner and outer races of said bearing solely by water repellency of a water-repelling film layer provided on at least said opposing surface of said first component, said sealing means having said micro clearance and said water-repelling film layer.
