Abstract
A lane rope float having higher wave absorbing performance than before is provided. A lane rope float is one that is attached to a rope R via a tubular portion and divides lanes of a pool, and the lane rope float is characterized by: including a plurality of blades that protrude from a side surface of the tubular portion in parallel with the rope R, and a wall surface portion that is coupled to side end portions of the blades to cover the blades, in which in an outer end portion of the lane rope float from the center of the tubular portion to the wall surface portion, at least ½ of the range from the center of the tubular portion to the wall surface portion is formed along a vertical plane V2 perpendicular to the tubular portion.

A lane rope float that is attached to a rope via a tubular portion and divides lanes of a pool, the lane rope float comprising:
- a plurality of blades that protrude from a side surface of the tubular portion in parallel with the rope;
- and
- a wall surface portion that is coupled to side end portions of the blades to cover the blades, wherein
- in an outer end portion of both sides of the lane rope float from a center of the tubular portion to the wall surface portion,
- an entire part extending from the center of the tubular portion has a length of at least ½ of a length from the center of the tubular portion to the wall surface portion and is formed along a vertical plane perpendicular to the tubular portion,
- openings are formed as being cut out, which are open respectively at a part of the wall surface portion in a direction of each outer end portion.

A lane rope float that is attached to a rope via a tubular portion and divides lanes of a pool, the lane rope float comprising:
- a plurality of blades that protrude from a side surface of the tubular portion in parallel with the rope;
- and
- a wall surface portion that is coupled to side end portions of the blades to cover the blades, wherein
- in one outer end portion of the lane rope float from the side surface of the tubular portion to the wall surface portion,
- an entire part extending from the side surface of the tubular portion has a length of at least ½ of a length from the side surface of the tubular portion to the wall surface portion and is formed into a convex shape or a concave shape, and
- the other outer end portion of the lane rope float is formed into a concave shape or a convex shape so as to correspond to the convex shape or the concave shape of the one outer end portion,
- openings are formed as being cut out, which are open respectively at a part of the wall surface portion in a direction of both sides of the outer end portion.
