## Abstract

A line roller for guiding a fishing line to a spool of a spinning reel includes a bearing member rotatable about a rotational axis. The line roller also includes a guide member disposed outside the bearing member in a radial direction from the rotational axis. The guide member includes a holding portion and a body. The holding portion is made of a metal or a ceramic. The holding portion is to hold a fishing line. The holding portion extends in a circumferential direction centered about the rotational axis. The body includes a resin, and a guide surface for leading the fishing line to the holding portion.

## Claims

### Claim 1

A line roller for guiding a fishing line to a spool of a spinning reel, the line roller comprising:
a bearing member rotatable about a rotational axis; and
a guide member disposed outside the bearing member in a radial direction from the rotational axis, the guide member including a holding portion and a body, the holding portion made of a metal or a ceramic, the holding portion to hold the fishing line, the holding portion extending in a circumferential direction centered about the rotational axis, the body including a resin, and a guide surface for leading the fishing line to the holding portion.

### Claim 2 (depends on 1)

The line roller according to claim 1, wherein
the body includes a recess annularly extending in the circumferential direction, and
the holding portion is accommodated within the recess.

### Claim 3 (depends on 1)

The line roller according to claim 1, wherein
the body includes a first body and a second body, and
the holding portion is interposed and held between the first body and the second body.

### Claim 4 (depends on 1)

The line roller according to claim 1, wherein
the body includes a first body and a second body disposed at an interval away from the first body in a direction parallel to the rotational axis, and
the holding portion is disposed between the first body and the second body.

### Claim 5 (depends on 1)

The line roller according to claim 1, wherein the holding portion includes an annular groove for holding the fishing line.

### Claim 6 (depends on 1)

The line roller according to claim 1, wherein the guide surface tilts at an angle of 10 to 60 degrees relative to the rotational axis.

### Claim 7 (depends on 1)

The line roller according to claim 1, further comprising:
a support member engaging the guide member and contacting a first end surface of the bearing member, wherein
the guide member includes a contact portion contacting a second end surface of the bearing member opposite to the first end surface of the bearing member.

### Claim 8 (depends on 1)

The line roller according to claim 1, further comprising:
a first restriction member abutting the bearing member; and
a second restriction member abutting the bearing member,
the bearing member interposed between the first and second restriction members in a direction parallel to the rotational axis.

### Claim 9

A guide member rotatable about a rotational axis, the guide member comprising:
a holding portion including a metal or a ceramic, the holding portion having an annular groove and an outermost surface, the holding portion extending in a circumferential direction centered about the rotational axis, the outermost surface being a surface of the holding portion farthest from the rotational axis; and
a body including a resin, and having a guide surface abutting the outermost surface of the holding portion.

### Claim 10 (depends on 9)

The guide member according to claim 9, wherein
the body further includes a recess annularly extending in the circumferential direction, and
the holding portion is accommodated within the recess.

### Claim 11 (depends on 9)

The guide member according to claim 9, wherein
the body further includes a first body and a second body, and
the holding portion is interposed and held between the first body and the second body.

### Claim 12 (depends on 9)

The guide member according to claim 9, wherein
the body further includes a first body and a second body, the first body and the second body abuts the holding portion, and
the holding portion separates the first body from the second body.

### Claim 13 (depends on 9)

The guide member according to claim 9, wherein the guide surface tilts at an angle of 10 to 60 degrees relative to the rotational axis.
