Utility Model Publication No. 42-20330 or Utility Model Publication No. 1973-
As shown in Publication No. 152701, two flanges are provided on the outside, spokes are assembled between the two flanges and the rim, and the spokes firmly connect the hub and rim via the flanges. are doing. The shape of the flange of the hub is circular, and a large number of spoke attachment holes are provided on the circumference near the outer periphery of the flange. The spokes are mounted diagonally in the radial direction between the hub and the rim, intersecting each other, but in order to prevent strong contact at the intersecting points of the spokes, the bases of the spokes are attached to one flange. It is inserted into every other hole from the inside and outside, and the axis of the spoke is shifted and fixed. Therefore, the base of the spoke inserted from inside the flange is bent at an acute angle and is easily damaged.
ところで、最近は省エネルギ対策の一環として
車両の軽量化が叫ばれ、種々検討されているが、
本考案は、その一構成部品であるハブを軽量化し
ようとするものである。 By the way, recently there has been a call for reducing the weight of vehicles as part of energy saving measures, and various studies are being carried out.
The present invention aims to reduce the weight of the hub, which is one of its components.
一般に円に内接する多角形は、その円より面積
が小さくなり、多角形の角数が少ない程面積が小
さくなる。従つてフランジをできるだけ角数の少
ない多角形にすれば、ハブを軽量化できるもので
ある。 Generally, a polygon inscribed in a circle has a smaller area than the circle, and the smaller the number of angles of a polygon, the smaller the area. Therefore, by making the flange a polygon with as few angles as possible, the weight of the hub can be reduced.
しかしながら、軽量化と強度保持とは相反する

が、削除量はわずかであり、軽量化の効果として
は、非常に小さい。 However, reducing weight and maintaining strength are contradictory issues, and it is necessary to consider making the spoke mounting holes polygonal while maintaining their strength. For example, in a conventional circular flange, if the outer periphery between the spoke mounting holes is simply removed linearly to make it polygonal,
Although the weight is reduced and there is almost no decrease in strength, the amount removed is small and the weight reduction effect is very small.
本考案は、スポーク取付穴の強度を充分保持し

る。 The present invention aims to significantly reduce weight by increasing the amount of removal while maintaining sufficient strength of the spoke mounting holes. Spoke mounting holes are arranged on the large pitch circle and on the small pitch circle, and each spoke mounting hole on the pitch circle is placed approximately in the middle of the spoke mounting hole drilled on the large pitch circle, and on the small pitch circle. The spoke mounting holes are arranged alternately so that the spoke mounting holes are located alternately, and the spoke mounting holes on the large pitch circle are linearly deleted to form a regular polygon with a small number of angles. As a result, the amount of deletion becomes large, and the weight reduction becomes larger.
