Abstract

PROBLEM TO BE SOLVED: To prevent upward parting of the tip part of a bit fitted in a fitting groove of a vis and a screw by arranging recessed grooves in the lengthwise direction on the side surfaces of planar view cross-shaped blades. SOLUTION: In forming four blades 1, 2, 3, 4, recessed grooves 5 are cut/ formed in the lengthwise direction on the respective both end surfaces of these four blades 1, 2, 3, 4. The recessed grooves 5 are recessed grooves 5 by forming a pair of projecting shapes 5A, 5B on the respective both side surfaces of the four blades 1, 2, 3, 4 in a juxtaposed state, and these projecting shapes 5A, 5B are cut/formed at the same curving rate as a bottom curve between the blades 1, 2, 3, 4. Thus, when the blades 1, 2, 3, 4 are rotated by being fitted in a fitting groove of a machine screw and a screw, the recessed grooves 5 arranged in the lengthwise direction of the side surfaces of the blades 1, 2, 3, 4 are put in a state of biting in an inner wall of the fitting groove of the machine screw and the screw to thereby reliably prevent upward parting of the tip part of a bit from the fitting groove of the machine screw and the screw.
