  • Patent number: 11997996
    Abstract: A spool braking device includes a brake drum and a rotation structure. The brake drum is disposed in a reel body and positioned alongside a spool in an axial direction. The rotation structure is arranged between the spool and the brake drum in the axial direction. The rotation structure has a support, a brake shoe, and a biasing member. The support rotates in accordance with a spool shaft. The brake shoe has a center of gravity arranged outside of the brake drum in a radial direction. The brake shoe is configured to contact a tapered surface of the brake drum. The biasing member biases one of the support or the brake drum towards another one of the support or the brake drum. The one of the support or the brake drum is movable in the axial direction with respect to the another one of the support or the brake drum.

  • Publication number: 20240138387
    Abstract: Provided is a sound generation mechanism including a rotation member configured to rotate together with a spool and including a recess-protrusion portion formed on an outer peripheral surface along a circumferential direction of the rotation member; a contacting member moveably supported relative to a pivot shaft and configured to elastically move relative to the recess-protrusion portion of the rotation member; a biasing member configured to bias the contacting member to a predetermined position; and a restriction member configured to restrict movement of the contacting member in an axial direction of the pivot shaft. With this mechanism, detachment or damage of a retaining ring due to movement of a contacting member can be suppressed.

  • Patent number: 11654645
    Abstract: A frictional power transmission belt includes a tension layer forming a belt back surface, a compression rubber layer to be in contact with a pulley and frictionally engaged with the pulley, and a tension member embedded between the tension layer and the compression rubber layer along a belt length direction. The compression rubber layer has a surface to be in contact with the pulley. At least a part of the surface is coated with a fiber layer via a fiber/resin mixture layer. The fiber/resin mixture layer contains a resin component and heat-resistant fibers having a softening point or a melting point higher than a vulcanization temperature of a rubber forming the compression rubber layer. The fiber layer contains hydrophilic heat-resistant fibers having a softening point or a melting point higher than the vulcanization temperature and does not contain a resin component.
