PURPOSE:To evenly bear the load by all bolts even against the lateral slipping force by fixing the bolts and the fixing metals which are connected to an electric machine. CONSTITUTION:An electric machine 1 is fixed to a foundation 3, by screwing a foundation bolt 4 which is embedded in the foundation 3 and a fixing metal 5a which is connected to the bottom of the machine 1 by using a bolt 6a. In this case, both the bolt 6a and the hole of the metal 5a are tapered. When the bolt 5a is tightened, the tapered portion of the bolt 6a is perfectly contacted with the tapered hole of the metal 5a and fixed. In this constitution, all the bolts evenly bear the load against the lateral slipping force, the adequate length of the diameter of each bolt and the adequate number of the bolts can be selected, and the economical and stable fixing apparatus can be obtained. |
