Summary:To provide a force transmission device that allows the force from pressing means to be easily transmitted to a rock bolt even if a center line of a force transmission shaft of the pressing means and the center line of the rock bolt are not located on the same straight line, and can improve the work efficiency of inserting the rock bolt into a hole.SOLUTION: A force transmission device of the present invention is provided between pressing means (rock drill) and a rock bolt and transmits the force from the pressing means to the rock bolt when driving the rock bolt comprises a rear transmission shaft whose rear end is attached to the pressing means, a front transmission shaft 13 with the rock bolt attached to its front end, an intermediate transmission shaft 12 provided between the rear transmission shaft and the front transmission shaft, rear connecting means for connecting the front end of the rear transmission shaft and the rear end of the intermediate transmission shaft, and front connecting means 16 connecting the front end of the intermediate transmission shaft and the rear end of the front transmission shaft. The rear connecting means and the front connecting means include a sliding mechanism 6 and a limiting mechanism 7 that limits the sliding range of the sliding mechanism.SELECTED DRAWING: Figure 4 【課題】押圧手段の力伝達軸の中心線とロックボルトの中心線とが同一直線上に位置しない状態となったとしても、押圧手段からの力がロックボルトに伝わりやすくなり、ロックボルトを孔に挿入する作業の作業効率を向上できる力伝達装置を提供する。【解決手段】ロックボルトを打設する際に、押圧手段（削岩機）とロックボルトとの間に設けられて押圧手段からの力をロックボルトに伝達する本発明の力伝達装置は、押圧手段に後端部が取付けられた後側伝達軸と、前端部にロックボルトが取付けられた前側伝達軸１３と、後側伝達軸と前側伝達軸との間に設けられた中間伝達軸１２と、後側伝達軸の前端部と中間伝達軸の後端部とを連結する後側連結手段と、中間伝達軸の前端部と前側伝達軸の後端部とを連結する前側連結手段１６とを備え、後側連結手段、及び、前側連結手段は、摺動機構６と、摺動機構の摺動動作範囲を制限する制限機構７とを備えたことを特徴とする。【選択図】図４
