The one-way clutch in the fishing reel disclosed in Japanese Unexamined Patent Publication No. 7-18568 and a fishing reel disclosed in Japanese Unexamined Utility Model Publication No. The outer periphery of the support portion of the reel body into which the outer ring is fitted is also formed into a non-circular cross section of the same shape, and the outer ring is fitted into the inner periphery of the support portion to rotate the one-way clutch around the support portion of the reel body. Stop fitting. However, in this non-rotating fitting type mounting structure, the outer periphery of the outer ring formed in a different shape and the inner periphery of the support portion are firmly attached without looseness while ensuring concentricity with the drive shaft. The outer peripheral portion and the non-circular portion on the inner periphery of the support portion of the reel body must be machined with high precision, and high-precision machining is required. However, its processing is difficult. In addition, this has caused an increase in product cost. Also, in practice, backlash is likely to occur in the fitted portion, and it is difficult to obtain a reverse rotation preventing function with a small degree of reverse play due to the wedge action of the rolling one-way clutch.

い。When the outer race of the one-way clutch is strongly press-fitted into the support portion of the reel body and fitted, the inner and outer peripheral surfaces to be fitted to each other are non-circular in cross section, causing abnormal deformation. If there is a processing error between the parts, as the press-fitting becomes stronger, the eccentricity follows the error and the eccentricity tends to be shifted. Is easily damaged. As a result, there are problems that the rotation of the drive shaft becomes heavy and the wedge action of the one-way clutch is impaired. Conventionally, the reel body is often made of resin to reduce the weight, but in this case, the fitting receiving part is soft, so the fitting part is deformed or worn due to a strong load and impact when preventing reverse rotation. As a result, there is a possibility that so-called rattling occurs, and the reverse rotation prevention device does not function early. It is not preferable to increase the diameter of the outer ring of the one-way clutch or the like to reinforce the detent engagement portion, because the entire reel also increases in size.

るので好ましくない。In the fishing reel disclosed in Japanese Utility Model Laid-Open Publication No. 6-5467, the outer circumference of the outer ring of the one-way clutch is formed into a circular cross section in order to improve the fitting accuracy of the rolling one-way clutch to the reel body. On the other hand, a locking portion formed on the end surface of the outer ring of the one-way clutch is engaged with a locking portion receiver formed on the abutting end surface of the reel body, and a locking function of the outer ring is provided. It is what you have. This method can be expected to improve the centering accuracy of the rolling type one-way clutch on the reel body, but the locking part consisting of the convex and concave parts formed on the end surface of the cylindrical outer ring of the one-way clutch is used to prevent reverse rotation. Since a strong load and impact are directly applied, both engaging portions are likely to be deformed, broken or worn, and play occurs early, so that the rolling type one-way clutch has a reverse playability by a so-called wedge action. It is difficult to obtain the reverse rotation preventing function with less noise. In this case, especially when the reel body is made of resin in order to reduce the weight, the engagement portion is also softened, and the deformation and wear of the engagement portion are more remarkable. There is a possibility that it will not be done. Also, if the diameter of the one-way clutch component is increased to reinforce the detent engagement portion, the entire reel is also undesirably increased in size.

れる。As described above, according to the present invention, the rotation of the outer ring of the one-way clutch held on the support portion of the reel body is stopped by another detent member. Can easily be positioned, and the assembled state of the one-way clutch is stabilized. Also, when fitting the outer ring of the one-way clutch into the fitting portion of the support portion of the reel body, there is not much need to strongly push and fit, and the assembling is simple, and assembling workability is improved, Since there is not much need to push and fit the outer ring of the one-way clutch strongly into the support part of the reel body, an abnormal deformation phenomenon that is likely to occur when pushing and fitting strongly, that is, the error between the fitting parts is the axis center It can be avoided as much as possible to express as a deviation. Therefore, high-precision machining is not required, concentricity with the rotary drive shaft is not impaired, and a reverse rotation preventing function with a small reverse play due to the wedge action of the rolling one-way clutch can be obtained.

共に、リール全体の軽量化も可能となる。Further, since a strong load or impact force applied to the outer ring of the one-way clutch at the time of reverse rotation is dispersed to a portion other than the outer ring of the one-way clutch via the detent member, a direct load on the mounting portion of the outer ring is provided. And the impact force are reduced, and deformation and wear of the outer ring mounting portion are prevented. Therefore, the switching operation of the rolling one-way clutch can be stabilized by rotating the retainer, and the high-precision reverse rotation preventing function without rattling can always be maintained for a long time. Further, it is possible to use a material such as a resin having relatively low strength for the support portion of the reel body, the outer ring of the one-way clutch, and the like, thereby making it possible to reduce the cost of manufacturing parts and to reduce the weight of the entire reel.
