The screwing device of the above-described embodiment has the above-mentioned structure and can be used as described above, and therefore has the following advantages.

That is, the device body 1 can be easily moved by the wheels 11 provided on the rear surface side of the device body 1, and during the screwing work, the slippage located below the lower surface of the wheel 11 can be achieved. Since the stopper member 15 contacts the plate member 67 and the screw 11 can be screwed in the state where the wheel 11 is separated from the plate member 67, there is an advantage that the device body 1 does not unexpectedly move during the screwing operation. Have.

Further, since the anti-slip member 15 contacts the plate member 67, the device body 1 does not slip during the screwing operation, and the holding member 41 can be reliably positioned above the screwing place. it can. In particular, since the weight of the operator acts on the anti-slip member 15 via the step 13, the anti-slip member 15 can be pressed against the plate member 67 to prevent the device body 1 from slipping more reliably.

Further, since the screw member 61 is held by the spherical bodies 49 and 50 provided in the upper and lower sides, respectively, the screw member 61 is fixed by the feeding member 31 while adjusting the position angle of the blade portion 64. Unlike the conventional device, the screw member 61 can be properly held by the holding member 41 without feeding.

Further, the shaft portion 63 of the screw member 61 is brought into contact with the lower spherical body 50, the head portion 62 is locked by the upper spherical body 49, and the screw member 61 is accurately rotated with the head portion 62. The screw member 61 can be held at a position where it can be engaged with the distal end portion 27a of the member 27, and the spherical members 49 and 50 are arranged vertically.
Since the screw member 61 is held, the screw member 61 can be held while preventing the screw member 61 from being displaced in the axial direction.

Further, since the spherical body 50 is provided such that the distance from the screwing-in place is approximately half of the screw member 61, the spherical body 50 contacts the screw member 61 until the screw member 61 is screwed in approximately half. Since they are in contact with each other, there is an advantage that tilting of the screw member 61 can be prevented until the tip portion comes into contact with the plate member 67 and when the shaft portion 63 is screwed.

Further, when the air motor 25 descends to a certain position, the cylinder 17 and the rotating means 25 are stopped by the limit switch 35, and the screwing work is completed. Therefore, it is necessary for the operator to perform the operation of stopping the contraction of the cylinder 17. As a result, unlike the conventional device, the device body 1 does not rise, and the rotating member 27 can be prevented from being damaged.

Further, the screwing device can also perform the screwing operation of other screw members having no wing portion 64, especially even in the case of screw members having different lengths of the shaft portion 63. In the case of the screw member 61 having the shaft portion 63 having a length longer than the distance between the screwing place and the lower spherical body 50, the tilting of the screw member 61 until the tip portion contacts the screwing place is prevented. It has the advantage that
