## Abstract

A pass-through fishing rod comprising a line support and retainers prevents a fishing line from contacting the inner surface of a rod or water adhering to the inner surface and enables the line to be drawn out and rolled up smoothly. The line support pitch of the line support supporting a fishing line is smaller than the retention pitch of the retainers for retaining the line support spaced from the inner surface of the rod.

## Claims

### Claim 1

A pass-through fishing rod having a shaft center and an inner surface, said rod having a line support which comprises a plurality of line support sections having a line support pitch, said line support sections being spaced along said shaft center of said rod for supporting a fishing line and retained within said rod by a plurality of retainers including a front retainer, a rear retainer and a plurality of intermediate retainers, said retainers having a retention pitch, wherein said line support pitch of said line support sections is smaller than said retention pitch at which said line support is retained within said rod by said plurality of retainers while spaced from said inner surface of said rod, and wherein said line support comprises a spiral and a thin cylinder externally fit to the spiral.

### Claim 2 (depends on 1)

The pass-through fishing rod of claim 1 wherein said thin cylinder is formed of a thermally contracting tube externally fitted to said spiral.

### Claim 3 (depends on 1)

The pass-through fishing rod of claim 1 wherein said intermediate retainers are formed with a central aperture, said central aperture being formed with a tapered surface.

### Claim 4 (depends on 1)

The pass-through fishing rod of claim 1 wherein said intermediate retainers are formed with at least one axially extending protrusion on an outer surface thereof which extends into a groove formed on an inner surface of said rod.

### Claim 5 (depends on 1)

The pass-through fishing rod of claim 1 wherein said intermediate retainers are formed with at least one axially extending groove on an outer surface thereof which receives a protrusion formed on an inner surface of said rod.

### Claim 6 (depends on 1)

The pass-through fishing rod of claim 1 wherein said intermediate retainers are formed with at least one axially extending groove on an outer surface thereof which receives a protrusion formed on an inner surface of said rod and said thin cylinder is formed with at least one axially extending groove on an outer surface thereof which receives a protrusion formed on an inner surface of said rod.
