| 发明名称 | Universal joint and yoke | ||
| 摘要 | A universal joint includes a pair of yokes and a joint cross. The pair of yokes have mutually identical shapes. Each of the yokes has a proximal portion and a pair of arm portions at which the joint cross is mounted. The proximal portion has an insertion hole for mounting a shaft, a slit formed along the insertion hole and a bolt insertion hole for fastening the slit. A positional relationship between the proximal portion and the pair of arm portions is set such that a line segment that connects the pair of arm portions to each other and an insertion direction in which a bolt is inserted in the bolt insertion hole intersect with each other at 45°. The bolt insertion holes of the pair of yokes coupled by the joint cross face the same side. | ||

| 主权项 | 1. A yoke integrally comprising: a proximal portion; a pair of arm portions that extend from the proximal portion, the pair of arm portions being used for mounting a joint cross; a rib portion that projects from the proximal portion toward bases of the pair of arm portions; and a pair of flanges, wherein a base adjacent to the rib portion is thick so as to rise toward the counterpart arm portion, the proximal portion has an insertion hole for mounting a shaft, a slit formed along the insertion hole and a bolt insertion hole for fastening the slit, a positional relationship between the proximal portion and the pair of arm portions is set such that a line segment that connects the pair of arm portions to each other and an insertion direction in which a bolt is inserted in the bolt insertion hole intersect with each other at 45°. | ||
