## Abstract

A roller clutch includes an outer ring, an inner ring, a rollers, a torsion spring, and a housing member. The roller is disposed between the inner ring and the outer ring. The roller i configured to move between a transmitting position and a non-transmitting position. The spring biases the roller to the transmitting position. The housing member has a housing hole and an inner wall surface. The housing hole houses the torsion spring. The inner wall surface defines the housing hole and is configured to support the torsion spring.

## Claims

### Claim 1

A roller clutch for a fishing reel, comprising:
an outer ring including a radially inner side;
an inner ring disposed on the radially inner side of the outer ring;
a roller disposed between the inner ring and the outer ring, and configured to move between a transmitting position to transmit power between the outer ring and the inner ring and a non-transmitting position to prevent transmission of the power;
a torsion spring configured to bias the roller toward the transmitting position; and
a housing member having a housing hole housing the torsion spring, the housing hole being defined by an inner wall surface, the inner wall surface supporting the torsion spring on an outer surface thereof.

### Claim 2 (depends on 1)

The roller clutch for a fishing reel according to claim 1, wherein
the housing hole having a bottom surface that is a flat surface.

### Claim 3 (depends on 1)
