ボルトＤで取着されているため交換に手間がかか
つて都合が悪い。 Motorcycles are driven by connecting the engine sprocket and rear wheel sprocket with a chain. Generally, as shown in FIGS. 1 and 2, a flange B is provided on one side of the hub A of the rear wheel, a disc-shaped sprocket C is aligned with the flange B, and the flange B is Bolts D are passed through sprocket C at several points around the circumference and tightened with nuts E, and sprocket C is attached to hub A of the rear wheel. by the way,
There are types of motorcycles that are used for racing, and in these types of motorcycles, the sprocket can be changed to have a different number of teeth to suit the slopes of the racetrack, and the speed can be adjusted to suit the racetrack. That's what I do. In this case, the sprocket C is attached with several bolts D, which is inconvenient because it takes time and effort to replace.
この考案は、かかる点に鑑み、スプロケツトの

下本考案を第３図及び第４図に示す実施例につい
て説明する。 In view of these points, this invention has been improved to shorten the sprocket replacement time.The invention will be described below with reference to an embodiment shown in FIGS. 3 and 4.
後輪のハブ１の一側に鍔部２を設ける。そし

は車軸、１１はスポークである。 A flange portion 2 is provided on one side of a hub 1 of a rear wheel. Several pins 3 are implanted all around the flange 2.
The sprocket 4 is a ring-shaped sprocket having teeth 5 on its outer periphery that mesh with a chain, and a pin hole 6 is provided to match the position of the pin 3. The sprocket 4 is aligned with the outside of the flange 2, and the pin 3 is fitted into the pin hole 6. The ring nut 7 has a flange 8 provided on the outside thereof, and is screwed into a screw provided inside the flange portion 2 of the hub 1 to press the inner peripheral edge of the sprocket 4. The ring nut 7 is provided with a notch 9 into which a spanner is attached. 10
is an axle, and 11 is a spoke.

and hub 1 can be aligned. Also, sprocket 4
Since the rotational force is received by the pin 3, the sprocket 4 does not move in the rotational direction. The ring nut 7 only needs to stop the sprocket 4 from separating from the flange. The sprocket 4 can be inserted and removed from the pin 3 by simply attaching and detaching one ring nut 7, reducing replacement time.

ツトが抜き差しして交換できるので、交換の手間
が簡単で短時間で交換できる。 As explained above, this idea involves providing a flange on one side of the hub and implanting a pin, fitting the pin into the pin hole of a disc-shaped sprocket, and aligning the inner periphery of the sprocket with the inner periphery of the flange. Since the sprocket and hub can be aligned by fitting the pin hole, the driving force is transmitted by the pin, so the ring nut only needs to hold the sprocket in place. . In the case of replacement, the sprocket can be inserted and removed by simply attaching and detaching one ring nut, so replacement is easy and can be done in a short time.
