The mechanism uses differential screws, eccentric cams, special adjustment jigs, etc., but the differential 7 and ji require special screws, which increases the cost, and the rotation is made to take advantage of the difference in screw pitch. There is a drawback that the adjustment range is determined by IIN, and in the case of an eccentric cam, the manner in which force is applied (direction) is not in a single direction, so deviations in other directions are likely to occur during adjustment, making accurate adjustment difficult. Also, since the amount of eccentricity is used, &I
There are drawbacks such as not being able to obtain a large value of &IvII. Special &1
The aHJ jig has drawbacks such as being difficult to handle and having a complicated structure, which reduces productivity.
