PROBLEM TO BE SOLVED: To provide a fastening device configured to prevent fluctuation of a carriage to fasten the carriage precisely even at positions whose heights from a leg member to the ground are different.SOLUTION: A fastening device 10 comprises a recessed part 402 provided in a protruding part 403, a leg member 13, a linearly moving cam 14 and a support rod 15. The protruding part 403 is provided on a lower surface 401 of a trestle 40. The support rod 15, provided to protrude from the recessed part 402 toward the leg member 13, which contacts a slope 142 of the linearly moving cam 14, can move in a horizontal direction and supports the leg member 13. With the support rod 15, the trestle 40 is directly fixed to the leg member 13 to prevent fluctuation of the carriage. Further, with the linearly moving cam 14, a position at which the support rod 15 supports the leg member 13 can be moved. This allows the support rod 15 to support the leg member 13 without depending on a height from the leg member 13 to the ground, so that the carriage can be fastened precisely even at positions at which heights of the ground are different and positions at which flatness of the ground is poor.SELECTED DRAWING: Figure 3
【課題】台車の揺動を防止し、脚部材から地面までの高さが異なる場所においても台車を精密に固定する固定装置を提供する。【解決手段】固定装置10は、凸部403に設けられる凹部402、脚部材13、直動カム14および支持棒15を備える。凸部403は、架台40の下面401に設けられている。支持棒15は、凹部402から脚部材13に向かって突出するように設けられ、直動カム14の斜面142に当接し、水平方向に移動可能で脚部材13を支持する。支持棒15によって、架台40と脚部材13とが直接固定され、台車の揺動を防止する。また、直動カム14によって、支持棒15が脚部材13を支持する位置が移動可能である。これにより、脚部材13から地面までの高さに依存しないで、支持棒15が脚部材13を支持することができる。したがって、地面の高さが異なる場所や地面の平面度が悪い場所においても精密に固定することができる。【選択図】図3
