Regarding the spoke wheels that are installed. In such a spoked wheel, each spoke generally includes a nipple rotatably connected to the rim, and a spoke with a circular cross section whose one end is screwed to the nipple and the other end is locked to the hub. Among the many spokes, spokes that are adjacent to each other in the axial direction of the axle are arranged so as to intersect with each other,
The spoke bodies at the intersection are close to each other or in contact with each other. Therefore, in order to increase the strength and rigidity of conventional spoked wheels, if the spokes were made thicker overall, the spokes would interfere with each other at the intersections, and there was a limit to how thick the spokes could be made. .

とする。 In order to achieve the above object, the present invention provides a structure in which a large number of spokes are stretched between a rim into which a tire is fitted and a hub that supports an axle, and the spokes that are adjacent to each other in the axial direction of the axle cross each other. In the spoke wheel, each spoke has a nipple rotatably connected to the rim, and a spoke main body, one end of which is screwed to the nipple and the other end of which is locked to the hub. The middle part of the spoke body, excluding the one end and the other end, has a wall thickness in the direction along the axle that is approximately the same as the outer diameter of the one end, and is along a plane perpendicular to the axle. The cross-sectional shape is formed into a substantially oval shape so that the wall thickness in the direction along the axle is greater than the wall thickness in the direction along the axle, and the wide side surfaces of the substantially oval portions face each other and intersect with each other.

ことができる。 An embodiment of the present invention will be described below with reference to the drawings. A rim 3 into which the tire 2 is fitted, and an axle 5
A large number of spokes 1 are stretched between the rim 3 and the hub 4 that supports the rim 3, and each spoke 1 is rotatably fitted and connected to a spoke support portion 3a provided at the center of the rim 3 in the width direction. A spoke body 1 having a nipple 1b and one end e1 screwed onto the nipple 1b.
a and the other end of the spoke main body 1a e 2
are locked in spoke locking holes 4a or 4b provided on both left and right sides of the hub 4, respectively. The one end e 1 and the other end e 2 of the spoke main body 1a
In the middle part m excluding the axle 5, the wall thickness t in the direction along the axle 5 is approximately the same as the outer diameter of the one end part e1 , and the wall thickness w in the direction along the plane perpendicular to the axle 5 is along the axle 5. The spoke bodies 1a of the spokes 1 that are adjacent to each other in the axial direction of the axle 5 among the many spokes 1 are formed at an intersection X 1 The spokes are disposed so as to intersect with each other in close proximity or contact with each other, and the wide side surfaces of the substantially oval cross-sectional portions of the spoke main body 1a face each other and intersect with each other. Therefore, the spoke main body 1a has a thicker middle part m compared to the conventional spoke main body 1a, which is formed to have a circular cross section over the entire length, and a significant increase in strength and rigidity is achieved. Moreover, the wall thickness t in the direction along the axle 5 of the middle part m of the spoke main body 1a
is suppressed to be substantially the same as that of both end portions e 1 and e 2 , so that the strength of the spoke bodies 1 a and 1 a at the intersection X 1 is reduced without reducing the strength against twisting and bending of the intermediate portion m. Interference can be avoided.

を効果的に防止し得る。 As described above, according to the present invention, a large number of spokes are stretched between the rim into which the tire is fitted and the hub that supports the axle, and the spokes that are adjacent to each other in the axial direction of the axle cross each other. In the arranged spoke wheel, each spoke is
Consisting of a nipple rotatably connected to the rim, and a spoke main body whose one end is screwed to the nipple and whose other end is locked to the hub,
The intermediate portion of the spoke, excluding the one end and the other end, has a wall thickness in the direction along the axle that is approximately the same as the outer diameter of the one end, and a wall thickness in the direction perpendicular to the axle. The cross-sectional shape is formed into a substantially oval shape so as to be larger than the wall thickness in the direction along the axle, and the wide side surfaces of these substantially oval portions face each other and intersect with each other, so that the spoke main body intermediate portion By increasing the thickness of the spoke body, the overall strength and rigidity of the spoke itself and, by extension, the spoke wheel can be greatly improved. Furthermore, although the spoke main body intermediate portion is made thicker as described above, its wall thickness in the direction along the axle can be kept approximately the same as that of both ends, so that the strength against torsion and bending of the intermediate portion is reduced. Interference between the spoke bodies at the intersection can be avoided without causing interference. Moreover, since the strength against twisting and bending of the intermediate portion of the spoke body does not decrease as described above, even when the nipple is tightened and rotated to assemble the wheel, the intermediate portion of the spoke body rotates together and is not forced to twist. This contributes to improving the efficiency of assembly work, and even when a large load is applied to the rim, bending deformation of the middle portion of the spoke body can be effectively prevented.
