Abstract

PURPOSE: To fix parts accurately without jigs by causing corresponding reference faces to adhere to one another in respect to a base stand and a yoke where three reference faces vertical to one another are provided respectively.
CONSTITUTION: Base stand 1 is provided with X', Y' and Z' faces orthogonal to one another as contact reference faces for permanent magnet 2 and yoke 3, and these faces correspond to X, Y and Z faces of yoke 3 and are caused to adhere to them respectively. Then, cut 32 is provided in the connection part between X' and Y' faces of base stand 1, and a prescribed step is formed between the Z' face of base stand 1 and plane 30. As a result, parts can be fixed accurately without jigs.
