[0021] (First embodiment) The configuration of the outdoor-usable part 1 according to the first embodiment will be described. Figures 1 and 2 are used to explain the configuration of the outdoor-usable part 1 according to the first embodiment. The outdoor-usable part 1 is a part that can be used outdoors, and can be used for at least one of a human-powered vehicle and a fishing tackle. The outdoor usable part 1 used in a human-powered vehicle includes at least one of a brake operating device for a human-powered vehicle, a suspension operating device for a human-powered vehicle, a seat post operating device for a human-powered vehicle, a front sprocket for a human-powered vehicle, a rear sprocket for a human-powered vehicle, a crank arm for a human-powered vehicle, a bottom bracket assembly for a human-powered vehicle, a rear derailleur for a human-powered vehicle, a front derailleur for a human-powered vehicle, a pedal for a human-powered vehicle, a suspension for a human-powered vehicle, a seat post for a human-powered vehicle, a drive unit for a human-powered vehicle, a hub assembly for a human-powered vehicle, a wheel for a human-powered vehicle, a frame for a human-powered vehicle, a front fork for a human-powered vehicle, a stem for a human-powered vehicle, a head part for a human-powered vehicle, a handle for a human-powered vehicle, a bash guard for a human-powered vehicle, a mudguard for a human-powered vehicle, a helmet for a human-powered vehicle, and eyewear for a human-powered vehicle. The outdoor usable part 1 used for fishing tackle includes at least one of a fishing reel, a fishing rod, a fishing lure, and fishing eyewear.

[0022] The outdoor usable part 1 includes a resin 10 and at least one cellulose fiber 20 dispersed in the resin 10. The at least one cellulose fiber 20 preferably includes a plurality of cellulose fibers 20.

[0023] The resin 10 may be, for example, a bioplastic, an engineering plastic, or a general-purpose plastic. The bioplastic may include a biomass plastic and a biodegradable plastic. The biomass plastic may be, for example, selected from the group consisting of polyamide, polypropylene, polycarbonate, polyethylene, polyethylene terephthalate, polyurethane, polylactic acid, and polytrimethylene terephthalate. The polyamide may be, for example, selected from the group consisting of PA11, PA11T, PA610, PAMXD10, PA10T, and PA510. The biodegradable plastic may be, for example, selected from the group consisting of polybutylene adipate terephthalate, polybutylene succinate, starch polyester resin, polyhydroxyalkanoate, and polyethylene terephthalate succinate. The engineering plastic may be, for example, selected from the group consisting of polyamide, polyacetal, polybutylene terephthalate, polycarbonate, polyethylene terephthalate, and modified polyphenylene ether. The general purpose plastic is selected from the group consisting of polypropylene, polyethylene, polystyrene, polyvinyl chloride, and acrylonitrile butadiene styrene.

[0024] The cellulose fibers 20 are fibers made from cellulose, and are produced from, for example, pulp, cotton, sisal, bamboo, kenaf, hemp, banana, and ramie. The cellulose fibers 20 have a maximum cross-sectional length L1 of 3 nanometers to 100 micrometers, preferably 10 nanometers to 100 micrometers, and more preferably 10 nanometers to 20 micrometers. The maximum cross-sectional length L1 means the maximum diameter in a cross section perpendicular to the longitudinal direction of the cellulose fibers 20. It is sufficient that at least one of the cellulose fibers 20 contained in the resin 10 has a maximum cross-sectional length L1 of 10 nanometers to 100 micrometers.

[0025] When the maximum cross-sectional length L1 of the cellulose fibers 20 is 10 nanometers or more, the rigidity and strength of the outdoor-usable part 1 can be improved. When the maximum cross-sectional length L1 of the cellulose fibers 20 is 10 nanometers or more, aggregation of the cellulose fibers 20 can be suppressed, and the suppression of aggregation can improve the dispersibility of the cellulose fibers 20 in the resin 10. When the maximum cross-sectional length L1 of the cellulose fibers 20 is 100 micrometers or less, the contact area of ​​the cellulose fibers 20 with the resin 10 can be increased, and the increased contact area can improve the adhesion of the cellulose fibers 20 to the resin 10.

[0026] The cellulose fibers 20 have a maximum longitudinal length L2 of 30 nanometers or more and 10 millimeters or less. The aspect ratio, defined by dividing the maximum longitudinal length L2 by the maximum cross-sectional length L1, is preferably 10 or more and 1000 or less. By having an aspect ratio of 10 or more and 1000 or less, the cellulose fibers 20 are less likely to aggregate during production, and the rigidity and strength of the outdoor-usable part 1 can be improved.

[0027] 2, at least one cellulose fiber 20 includes a main body 21 and at least one branched portion 22 branched from the main body 21. The at least one branched portion 22 preferably includes a plurality of branched portions 22.

[0028] A procedure for manufacturing the outdoor-usable part 1 according to the first embodiment will be described. Fig. 3 and Fig. 4 are used to explain the procedure for manufacturing the outdoor-usable part 1. The outdoor-usable part 1 is formed by carrying out the processes of step S1 and step S2 shown in Fig. 3.

[0029] In step S1, the cellulose fibers 20 are fibrillated. The fibrillation method may be a known method, such as a mechanical treatment using a high-pressure homogenizer, an underwater counter collision method, a water jet method, a grinder method, a ball mill method, or a bead mill method. At least one branch portion 22 is formed in the main body 21 by the fibrillation process in step S1.

[0030] In step S2, the resin 10 and the cellulose fibers 20 are kneaded. For example, a kneading device 6 is used to knead the resin 10 and the cellulose fibers 20. The kneading device 6 includes a temperature control unit 61 and a screw 62. The internal temperature of the kneading device 6 is controlled to, for example, 150°C to 300°C. Pellets of the resin 10 are fed into the temperature control unit 61, the internal temperature of which is controlled, and the screw 62 is rotated. The resin 10 and the cellulose fibers 20 are kneaded by the rotation of the screw 62, and the cellulose fibers 20 are three-dimensionally dispersed in the resin 10.

[0031] By carrying out the processes of steps S1 and S2, an intermediate molding material 7 used to manufacture the part 1 that can be used outdoors as shown in Fig. 1 is formed. The intermediate molding material 7 is molded using a mold or the like to manufacture the part 1 that can be used outdoors. As shown in Fig. 5, in the part 1 that can be used outdoors, cellulose fibers 20 are dispersed in resin 10. As shown in Fig. 6, in the part 1 that can be used outdoors, a plurality of fibrillated cellulose fibers 20 are entangled with one another.

[0032] In the outdoor-usable part 1, the rigidity and strength of the outdoor-usable part 1 can be improved by dispersing the cellulose fibers 20 in the resin 10. Since the cellulose fibers 20 are naturally derived fibers, it is possible to reduce CO2 emissions during production, and to provide an environmentally friendly outdoor-usable part 1.

[0033] Second embodiment The configuration of the outdoor-usable part 2 according to the second embodiment will be described. FIG. 7 is used to describe the configuration of the outdoor-usable part 1 according to the second embodiment. The same reference numerals as in the first embodiment are used for configurations common to the first embodiment, and duplicated explanations will be omitted. The outdoor-usable part 2 according to the second embodiment differs from the outdoor-usable part 1 according to the first embodiment in that the outdoor-usable part 2 further comprises at least one carbon fiber 30 dispersed in the resin 10.

[0034] The carbon fibers 30 are dispersed in the resin 10 to improve the mechanical strength of the outdoor-usable part 2. The carbon fibers 30 may be PAN-based carbon fibers or pitch-based carbon fibers. The length and diameter of the carbon fibers 30 are not particularly limited.

[0035] A procedure for manufacturing the outdoor-usable part 2 according to the second embodiment will be described. Fig. 4 and Fig. 8 are used to explain the procedure for manufacturing the outdoor-usable part 2. The outdoor-usable part 2 is formed by carrying out the processes from step S1 to step S3 shown in Fig. 8. Step S1 and step S2 are the same processes as in the first embodiment, so the explanation of step S1 and step S2 will be omitted as appropriate.

[0036] In step S2, a material is generated in which cellulose fibers 20 are dispersed in resin 10. In step S3, the material formed in step S2 is melted, and the molten material is impregnated with carbon fibers 30. A material in which cellulose fibers 20 and carbon fibers 30 are dispersed in resin 10 is generated by impregnating the material formed in step S2 with carbon fibers 30.

[0037] By carrying out the processes from steps S1 to S3, an intermediate molding material 8 is formed, which is used to manufacture the outdoor-usable part 2 shown in Fig. 7. The intermediate molding material 8 is molded using a mold or the like to manufacture the outdoor-usable part 2.

[0038] Third embodiment The configuration of the outdoor-usable part 3 according to the third embodiment will be described. Fig. 9 is used to explain the configuration of the outdoor-usable part 3 according to the third embodiment. The same reference numerals as in the first embodiment are used for the configurations common to the first embodiment, and duplicated explanations will be omitted.

[0039] The outdoor usable part 3 comprises at least one first layer 4 and at least one second layer 5. The at least one first layer 4 is disposed on the at least one second layer 5. The first layer 4 comprises a resin 10 and at least one cellulose fiber 20. The second layer 5 comprises an additional resin 11 and at least one carbon fiber 30 dispersed in the additional resin 11.

[0040] As the additional resin 11, for example, a bioplastic, an engineering plastic, or a general-purpose plastic is used, similarly to the resin 10. The additional resin 11 may be the same type of plastic as the resin 10, or may be a different type of plastic.

[0041] Some of the cellulose fibers 20 contained in the first layer 4 may protrude from the surface of the resin 10. The cellulose fibers 20 protruding from the surface of the resin 10 are caught in the second layer 5, thereby improving the adhesion between the first layer 4 and the second layer 5.

[0042] The phrase "at least one" as used herein means "one or more" of the desired options. As an example, the phrase "at least one" as used herein means "only one option" or "both of two options" if the number of options is two. As another example, the phrase "at least one" as used herein means "only one option" or "any combination of two or more options" if the number of options is three or more. [Explanation of symbols]
