  • Patent number: 9930873
    Abstract: A set of fishline guides which are configured to be attached to a rod in an axial direction of the rod, each of the set of fishline guides includes a frame including a fixing portion configured to be attached to an outer surface of the rod, a ring holding portion to which a guide ring through which a fishline passes is attached, and a support leg connecting the fixing portion to the ring holding portion, the fixing portion being in a plane transverse to a plane of the ring holding portion. The frame includes a plurality of fiber-reinforced resin layers foamed by laminating a plurality of fiber-reinforced prepregs in which a reinforcing fiber is impregnated with a synthetic resin. A normal line to a plane of each of the fiber-reinforced resin layers forming the ring holding portion coincides with an axial direction of the ring holding portion.

  • Patent number: 6301821
    Abstract: The invention concerns a durable and good-operability fishing rod which is highly strong and is improved in specific rigidity by preventing excessive resin, reinforced fibers from leaning to one side, and resin pools. The fishing rod has a main layer (12) formed by winding a first prepreg provided by impregnating highly strong fibers with resin so that weight percentage becomes 25% or less so that the fibers are oriented in an axial length direction and a reinforcement layer (14, 16) formed by winding a second prepreg provided by impregnating highly strong fibers with resin so that the fibers are oriented in a direction crossing the fiber orientation of the main layer (12) on at least one side of the inside and outside of the main layer (12). The reinforcement layer (14, 16) is formed thinner than the main layer (12), and resin impregnation percentage of the second prepreg is set to substantially the same as that of the first prepreg.
