  In the conventional fishing reel, the inner peripheral surface of the bearing or pinion gear and the outer peripheral surface of the spool shaft are relatively rotated at a high load or at a high speed. If relative rotation is performed at a high load or high speed in this way, seizure may occur between the inner peripheral surface of the bearing or pinion gear and the outer peripheral surface of the spool shaft. Therefore, in order to prevent seizure, the bearing or pinion gear Oil and grease are filled between the inner peripheral surface of the shaft and the outer peripheral surface of the spool shaft. However, since oil and grease flow out due to intrusion of seawater, washing after use, etc., fishers frequently replenish oil and grease between the inner peripheral surface of the bearing and pinion gear and the outer peripheral surface of the spool shaft. Need arises.

  An object of the present invention is to improve the wear resistance of the spool shaft and reduce the frictional resistance between the inner peripheral surface of the bearing or pinion gear and the outer peripheral surface of the spool shaft.

  A fishing reel according to a first aspect of the present invention is a fishing reel that winds and feeds a fishing line, and includes a spool, a spool shaft, and a DLC layer. The spool is a cylindrical member that winds fishing line around the outer periphery. The spool shaft is a metal member attached to the inner periphery of the spool. The DLC layer is formed on the surface layer side of the spool shaft by a DLC film forming process.

  In this fishing reel, since a DLC (Diamond Like Carbon, diamond-like carbon) layer is formed on the surface layer side of the spool shaft, the wear resistance of the spool shaft is improved, and the inner peripheral surface of the bearing and pinion gear and the spool are improved. The frictional resistance with the outer peripheral surface of the shaft can be reduced. Therefore, even if the angler bearing does not frequently replenish oil or grease between the inner peripheral surface of the pinion gear and the outer peripheral surface of the spool shaft, the angle between the inner peripheral surface of the bearing or pinion gear and the outer peripheral surface of the spool shaft is reduced. This makes it difficult for image sticking to occur.

  The fishing reel according to a second aspect of the present invention is the fishing reel of the first aspect, wherein the spool is made of a material having a specific gravity smaller than that of the metal used for the spool shaft. In this case, the weight of the spool can be reduced, and the inertia of the spool can be reduced, so that the spool can be rotated at a higher speed.

  A fishing reel according to a third aspect of the present invention is the fishing reel of the second aspect, wherein the spool is made of synthetic resin. In this case, for example, the spool can be formed by molding, so that the spool can be easily formed.

  A fishing reel according to a fourth aspect is the fishing reel according to the second aspect, wherein the spool is made of a magnesium alloy. In this case, the magnesium alloy can reduce the weight and the inertia of the spool.

  A fishing reel according to a fifth aspect is the fishing reel according to the second aspect, wherein the spool is made of an aluminum alloy. In this case, a relatively high strength and lightweight spool can be formed.

  A fishing reel according to a sixth aspect of the present invention is the fishing reel according to the fourth or fifth aspect, wherein the fishing reel is a double-bearing reel. The spool shaft is made of a stainless alloy that is fixed so as to be in direct contact with the inner peripheral portion of the spool. The DLC layer has an insulating property. In this case, since the insulating DLC layer is formed on the surface layer side of the spool shaft made of stainless steel that can be directly contacted with the spool made of magnesium alloy or aluminum alloy, electrolytic corrosion is caused between the spool and the spool shaft. Less likely to occur.

  A fishing reel according to a seventh aspect of the present invention is the fishing reel according to the sixth aspect, further comprising an anodized film layer formed on the surface layer side of the spool shaft. In this case, the corrosion resistance of the spool can be improved by forming an anodized film layer on the surface layer side of the spool.

  The fishing reel according to an eighth aspect of the present invention is the fishing reel of the seventh aspect, wherein the anodized film layer is formed by an anodizing process performed after the spool shaft is fixed to the spool. In this case, when anodizing is performed after the spool shaft is fixed to the spool, the insulating DLC layer is formed on the surface layer side of the stainless steel spool shaft, so that it is not necessary to mask the spool shaft.

  The fishing reel according to a ninth aspect of the present invention is the fishing reel according to any one of the first to eighth aspects, wherein the DLC layer is formed by a plasma ion film forming process which is a DLC film forming process. In this case, a DLC layer is formed on the surface side of the spool shaft by PBID (Plasma-Based Ion Deposition). The PBID method is a film forming process performed simultaneously with the PBII method, and a DLC layer is formed on the surface layer side of the second component main body by irradiating C ions. Here, a DLC layer having high adhesion to the spool shaft can be formed by plasma ion film formation.

  According to the present invention, since the DLC layer is formed on the surface layer side of the stainless steel spool shaft, the wear resistance of the spool shaft is improved, and the frictional resistance between the inner peripheral portion of the bearing and the outer peripheral portion of the spool shaft is improved. Can be reduced.

The engaging pin 16b penetrates the large-diameter portion 16a along the diameter, and both ends thereof protrude in the radial direction.

  Next, the surface structures of the spool 12 and the spool shaft 16 will be described.

  On the surface layer side of the spool 12, an anodized layer 81 (see FIG. 7) is formed by anodizing. The spool shaft 16 is fixed to the inner peripheral portion of the spool 12 and is formed of a stainless steel alloy. On the surface layer side of the spool shaft 16, a DLC layer 82 by PBID (Plasma-Based Ion Deposition) processing. (Diamond Like Carbon, diamond-like carbon layer, see FIGS. 5 to 7) is formed.

  Next, the surface treatment process of the spool 12 and the spool shaft 16 is shown in FIG.

  First, in step S1 shown in FIG. 4, a DLC layer 82 is formed on the surface layer side of the spool shaft 16 (see FIG. 5). The DLC layer 82 is formed by PBID (Plasma-Based Ion Deposition). The PBID method is a film forming process performed simultaneously with the PBII method, and the DLC layer 82 is formed on the surface layer side of the spool shaft 16 by irradiation with C ions.

  Next, in step S2 shown in FIG. 4, with the DLC layer 82 formed on the surface layer side of the spool shaft 16, the spool shaft 16 is fixed to the inner peripheral portion of the spool 12 so as not to rotate by serration coupling (FIG. 6). reference). It should be noted that the spool shaft 16 in a portion where the spool shaft 16 is not fixed to the inner peripheral portion of the spool 12 (on both sides of the spool 12) is exposed to the outside.

  In step S3 shown in FIG. 4, after the spool shaft 16 is fixed to the spool 12, an alumite layer 81 is formed on the surface layer side of the spool 12 (see FIG. 7). The anodized layer 81 is an oxide film formed by anodizing (alumite) of an aluminum alloy, and oxygen generated at the anode when electrolyzed in an electrolyte solution such as sulfuric acid using the aluminum alloy spool 12 as an anode. Therefore, an oxide film is formed. The alumite layer 81 is formed by three processes including pretreatment such as degreasing, etching, and neutralization, anodic oxidation treatment such as electrolytic treatment, and posttreatment such as sealing treatment. When performing the anodizing process, the spool shaft 16 is fixed to the spool 12 and is put into the electrolyte solution. Therefore, the portion where the spool shaft 16 is not fixed to the inner peripheral portion of the spool 12 (the spool 12 The spool shafts 16 on both sides are exposed to the outside and exposed to the electrolyte solution. Since the DLC layer 82 is formed on the surface layer side of the stainless steel spool shaft 16, the spool shaft made of stainless steel alloy is formed. There is no need to mask 16.

  Through the above steps, the DLC layer 82 is formed on the surface layer side of the spool shaft 16, and the alumite layer 81 is formed on the surface layer side of the spool 12.

  As shown in FIG. 2, the gear mechanism 18 includes a handle shaft 30, a main gear 31 fixed to the handle shaft 30, and a cylindrical pinion gear 32 that meshes with the main gear 31. The vertical position of the handle shaft 30 of the gear mechanism 18 is lower than the conventional position in order to reduce the height of the thumb rest 8. For this reason, the lower part of the 2nd side plate 5b and the 2nd side cover 6b which accommodates the gear mechanism 18 is located below the lower part of the 1st side plate 5a and the 1st side cover 6a.

  As shown in FIG. 2, the clutch engagement / disengagement mechanism 19 has a clutch yoke 40. The clutch yoke 40 is disposed on the outer peripheral side of the spool shaft 16 and is supported by two pins 41 (only one is shown) so as to be movable in parallel with the axis of the spool shaft 16. The clutch yoke 40 has an engaging portion 40a that engages with the constricted portion 32c of the pinion gear 32 at the center thereof. A spring 42 is disposed between the clutch yoke 40 and the second side cover 6b on the outer periphery of each pin 41 that supports the clutch yoke 40. The clutch yoke 40 is always urged inward by the spring 42. ing.

  With such a configuration, in the normal state, the pinion gear 32 is positioned at the inner clutch engagement position, and the meshing portion 32b and the engagement pin 16b of the spool shaft 16 are engaged to bring the clutch on state. It has become. On the other hand, when the pinion gear 32 is moved outward by the clutch yoke 40, the engagement portion 32b and the engagement pin 16b are disengaged and the clutch is turned off.

  The drag mechanism 21 includes a friction plate 45 that is pressed by the main gear 31 and a pressing plate 46 that presses the friction plate 45 against the main gear 31 with a predetermined force by rotating the star drag 3.

  The casting control mechanism 22 has a plurality of friction plates 51 arranged so as to sandwich both ends of the spool shaft 16 and a braking cap 52 for adjusting the clamping force of the spool shaft 16 by the friction plates 51. The left friction plate 51 is mounted in the brake case 65.

  As shown in FIG. 2, the centrifugal brake mechanism 23 includes a braking member 68 fixed to the brake case 65, a rotating member 66 arranged concentrically on the inner peripheral side of the braking member 68 and fixed to the spool shaft 16, Six moving members 67 mounted on the rotating member 66 so as to be movable in the radial direction are provided.

  In the dual-bearing reel having such a configuration, since the DLC layer 82 is formed on the surface layer side of the spool shaft 16 made of stainless steel, the wear resistance of the spool shaft 16 is improved, and the inner circumferences of the bearing 24a and the bearing 24b are improved. The frictional resistance between the portion and the outer peripheral portion of the spool shaft 16 can be reduced. Further, here, when performing anodizing on the surface of the spool 12, it is not necessary to mask the outer periphery of the spool shaft 16, so that the surface treatment process of the spool 12 can be simplified.
