Document Type and Number:
Japanese Patent JP2015183700
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a male screw facilitating the positioning of an attachment member and facilitating the detachment of the attachment member from an attachment target member.SOLUTION: A male screw 10 comprises: a male screw portion 11; a head portion 12; a pin portion 13; and a tool engagement portion 14. The head portion 12 includes a tapered portion 12a and a flat portion 12b. The tapered portion 12a slides along an inner surface of a storage portion 23a of an attachment target member 20. As a result, an axial direction of a pin portion 13 formed on the flat portion 12b is adjusted to be aligned with an axial direction of the storage portion 23a corresponding to an attachment position of an attachment member. The tool engagement portion 14 includes a fastening hole 14a and a detachment hole 14b. At a time of detaching the attachment member, the detachment hole 14b is rotated to generate an axial force in the male screw portion 11. The flat portion 12b of the head portion 12 transmits the axial force generated in the male screw portion 11 to the attachment member. As a result, the attachment member is displaced in a direction away from the attachment target member 20.
