った。However, in the above-mentioned conventional claw rest height adjusting device, in the former structure, the bolt-shaped adjusting shaft is oriented in the body axis direction, and the frame is close to the tip thereof. For this reason, the operation direction of the spanner is a direction perpendicular to the spanner, that is, a structure in which the span between the frame and the end surface of the body is rotated in parallel with the frame. For this reason, the operation space of the spanner is narrow and workability is poor, and the end shaft of the body cannot be operated continuously because it hinders the rotation operation of the spanner, which requires extra work time. There was such a problem. In the latter structure, a motor is required as a drive source for adjusting the height of the gripper supporting strip, and thus there is a problem that the device becomes large. In addition, since the linear motion is converted into the rotary motion in the drive transmission system, the load is large and it is easily damaged.If the load is not large to avoid the damage, the amount of movement of the slide wedge increases. There is also a problem that the height of the gripper supporting strip cannot be adjusted by a small amount because it cannot be taken.
