Abstract
A waterproof structure is provided on a spinning reel including a reel main body, a cylindrical member disposed on an outer periphery of a spool shaft and a rotor disposed at a front of the cylindrical member in the reel main body. The waterproof structure includes a seal member which waterproofs the entire circumference in the area between the cylindrical member and the rotor. The seal member includes a main lip that is in liquid-tight contact at a contact portion in the axial direction of the spool shaft. An annular wall portion is disposed on at least one of the rotor or the cylindrical member. The annular wall portion covers the contact portion at the entire circumference of an outer peripheral side of the contact portion.

A waterproof structure for a spinning reel including a reel main body, a cylindrical member disposed on an outer periphery of a spool shaft and a rotor disposed at a front of the cylindrical member in the reel main body, the waterproof structure comprising:
- a seal member configured to waterproof an entire circumference in an area between the cylindrical member and the rotor, the seal member including a main lip that is in liquid-tight contact at a contact portion in an axial direction of the spool shaft;
- and
- an annular wall portion disposed on one of the rotor or the cylindrical member, the annular wall portion configured to cover the contact portion along an entire circumference of an outer peripheral side of the contact portion;
- wherein the seal member further includes an auxiliary lip extending in the axial direction of the spool shaft with a gap axially provided between the cylindrical member and the rotor, the auxiliary lip disposed radially between the contact portion and the annular wall portion.
A spinning reel comprising:
- a reel main body;
- a spool including a spool shaft extending in an axial direction;
- a cylindrical member disposed on an outer periphery of the spool shaft;
- a rotor disposed at a front of the cylindrical member;
- and
- a waterproof structure including a seal member configured to waterproof an entire circumference in an area between the cylindrical member and the rotor, the seal member including a main lip that is in liquid-tight contact at a contact portion in the axial direction,
- wherein at least one of the rotor or the cylindrical member has an annular wall portion, the annular wall portion configured to cover the contact portion along an entire circumference of an outer peripheral side of the contact portion;
- and
- wherein the seal member further includes an auxiliary lip extending in the axial direction of the spool shaft with a gap axially provided between the cylindrical member and the rotor, the auxiliary lip disposed radially between the contact portion and the annular wall portion.
A waterproof structure for a spinning reel including a reel main body, a cylindrical member disposed on an outer periphery of a spool shaft and a rotor disposed at a front of the cylindrical member in the reel main body, the waterproof structure comprising:
- a seal member configured to waterproof an entire circumference in an area between the cylindrical member and the rotor, the seal member including a main lip that is in liquid-tight contact at a contact portion in an axial direction of the spool shaft;
- and
- an annular wall portion disposed on one of the rotor or the cylindrical member, the annular wall portion configured to cover the contact portion along an entire circumference of an outer peripheral side of the contact portion;
- wherein the main lip extends gradually from a radially inner side to a radially outer side towards the rotor in the axial direction.
A spinning reel comprising:
- a reel main body;
- a spool including a spool shaft extending in an axial direction;
- a cylindrical member disposed on an outer periphery of the spool shaft;
- a rotor disposed at a front of the cylindrical member;
- and
- a waterproof structure including a seal member configured to waterproof an entire circumference in an area between the cylindrical member and the rotor, the seal member including a main lip that is in liquid-tight contact at a contact portion in the axial direction,
- wherein at least one of the rotor or the cylindrical member has an annular wall portion, the annular wall portion configured to cover the contact portion along an entire circumference of an outer peripheral side of the contact portion;
- and
- wherein the main lip extends gradually from a radially inner side to a radially outer side towards the rotor in the axial direction.
