Title: Drilling rod
Inventor: FUKUDA ATSUO
IPC: E02D3/12
Filed: 1995-07-11
Abstract: PROBLEM TO BE SOLVED: To surely transfer rotating force and secure the strength against a twist by forming the cross sectional outer shape of the shaft section of a drilling rod into an ellipse. SOLUTION: The cross sectional outer shape of the drilling rod 1 of a drilling mixing machine is formed into an ellipse crushed with a circle from both sides.
