PROBLEM TO BE SOLVED: To provide a connection structure of a yoke of a universal joint and a shaft member, in which the yoke has sufficient shaft holding force, and which prevents abnormal abrasion of a female serration tooth and has excellent abrasion resistance, and provide a steering device having the connection structure.SOLUTION: In a state after an output shaft 7 is inserted into a connection part 30 and before the connection part 30 is fastened with a fastening bolt 45, a radial gap S is formed between a male serration 51 and a female serration 38. In the radial dimension of the gap S, a gap S1 of an axial insertion side end of the female serration 38 to be a side that the output shaft 7 is inserted is made larger than a gap S2 on an arm end side.SELECTED DRAWING: Figure 5

    【課題】ヨークが充分な軸保持力を備え、雌セレーション歯の異常な磨耗を防止し、耐摩耗性に優れた自在継手のヨークと軸部材との結合構造、および該結合構造を有するステアリング装置を提供すること提供すること。【解決手段】連結部30に出力軸7が挿入された後、締め付けボルト45によって連結部30が締め付けられる前の状態において、雄セレーション51と雌セレーション38との間には径方向の隙間Sが形成され、隙間Sの径方向寸法は、出力軸7が挿入される側である雌セレーション38の軸方向挿入側端の隙間S1ほうが、アーム端側の隙間S2よりも大きく形成されている。【選択図】図5
