To provide a foundation rod screw device for easily installing a pole or the like for racing on the snow in the ground or snow on the ground.
This foundation rod screw device 1 is composed of a passive rotating part 20, a driving rotating part 30, and a housing part 10 for holding the parts. With a claw 23 engaged with a cut 42, the passive rotating part 20 is fitted to the foundation rod 41 ((a), (b)), and a motor-driven drill driver 51 on sale is fitted to a driving shaft 31 of the driving rotating part 30 ((c), (d)). When the rotational power is applied from the motor-driven drill driver 51 to the driving shaft 31, the rotational power is applied through the driving rotating part 30 and the passive rotating part 20 to the foundation rod 41, so that the foundation rod 41 is screwed in the ground. Thus, the labor and time required by the work for installing a pole for racing on the snow which has been totally conducted manually can be reduced.
