| description | PROBLEM TO BE SOLVED: To provide a telescopic shaft and its manufacturing method, capable of reducing sliding resistance between a male-side shaft and a female-side shaft, and suppressing backlash.SOLUTION: A telescopic shaft 1 includes a male-side shaft 2 including a fitting shaft portion 21, and a hollow fitted portion 31, and the fitted portion 31 includes a male-side shaft 3 relatively movably fitted to the fitting shaft portion 21. The telescopic shaft 1 further includes an intermediate member 4 disposed between the fitting shaft portion 21 and the fitted shaft portion 31 and provided with a locking recessed portion 43 on an inner face, through holes 33, 45 penetrating through the intermediate member 4 from a bottom to an outer face of the locking recessed portion 43, and further penetrating through the fitted portion 31 from an inner face to an outer face, and fixing members 5 charged in the locking recessed portion 43 and the through holes 33, 45, and fixing the intermediate member 4 into the fitted portion 31. In relative movement of the fitting shaft portion 21 and the fitted portion 31, the fitting shaft portion 21 is slid to the inner face of the intermediate member 4 and a face at a fitting shaft portion 21 side, of the fixing member 5 charged in the recessed portion 43.SELECTED DRAWING: Figure 2
【課題】オス側シャフトとメス側シャフトとの間の摺動抵抗を低減しつつがたつきを抑制することができる伸縮軸およびその製造方法を提供する。【解決手段】伸縮軸１は、嵌合軸部２１を備えたオス側シャフト２と、中空の被嵌合部３１を備え、被嵌合部３１が嵌合軸部２１と相対移動可能に嵌合されたメス側シャフト３とを含む。また、伸縮軸１は、嵌合軸部２１と被嵌合部３１との間に介在し、内面に係止凹部４３が設けられた中間部材４と、中間部材４を係止凹部４３の底から外面まで貫通し、さらに、被嵌合部３１を内面から外面まで貫通する貫通孔３３，４５と、係止凹部４３および貫通孔３３，４５に充填され、中間部材４を被嵌合部３１内に固定する固定部材５とを含む。嵌合軸部２１と被嵌合部３１との相対移動時、嵌合軸部２１は、中間部材４の内面、および、凹部４３に充填された固定部材５の嵌合軸部２１側の面に対して摺動する。【選択図】図２ |
