Abstract
Abstract One end 10a of a bail arm return coil spring 10 mounted around a post 5 is extended into the bail mounting projection 4 on the side of the reel rotor 3. The extended end of the spring is given an L-shaped configuration and the down-turned end 11 of the spring is selectively engageable in any one of a plurality of accomodating holes 12, 12', 12"provided in the rotor housing wall 4a, whereby the biasing force applied by the bail arm spring may be quickly and easily changed.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
164 words
In a spin fishing reel including a reel body (1), a rotor (3) journalled for rotation in the body and drivenly engaged with a handle (2) mounted on the body, a pair of diametrically opposite support members (4) on the rotor, a pivot post (5) extending radially outwardly from each support member, bail arm means (6, 7, 8, 9) pivotally mounted on and extending between the posts, and a coil spring (10) mounted around one of the posts, one end of the spring being engaged with the bail arm means and the other end of the spring being engaged with the support member of said one post, whereby the spring biases the bail arm means toward a line retrieval position, spring tension adjustment means characterized by: (a) a plurality of circumferentially spaced spring end engagement means (12) disposed in said support member, and (b) said other end of the spring being configured to be selectively engageable with one of the spring end engagement means.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
77 words
A spin fishing reel as defined in claim 1, wherein said other end of the spring includes an elongated stem portion (10a) extending radially outwardly from the spring coil, and a locking portion (11) downwardly bent from the free end of the stem portion, whereby said other end of the spring has an L-shape, and wherein the radial distance of the locking portion from the coil axis coincides with the radial distance of the engagement means therefrom.
Claim 4
Dependent Claim
52 words
A spin fishing reel as defined in claim 1, wherein the engagement means comprises holes defined in said support member, and further comprising a cover plate (13) adapted to be mounted on said support member for protecting the coil spring and for retaining said other end thereof in a selected engagement means.
Claim 5
Dependent Claim
52 words
A spin fishing reel as defined in claim 2, wherein the engagement means comprises holes defined in said support member, and further comprising a cover plate (13) adapted to be mounted on said support member for protecting the coil spring and for retaining said other end thereof in a selected engagement hole.
