Document Type and Number:
Japanese Patent JP2018094093
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a pivotal shaft structure for scissors that improves the feeling of use by a user by reducing a quantity of its jumping out from a blade body surface.SOLUTION: A coil spring 6 is fitted by being inserted such that a shaft part 4a of a shaft member 4 and a shaft part 5a of a shaft member 5 face respective through-holes 2c in respective blade bodies 2, and in a state of being mutually threadedly engaged and connected, one end contacts with a head part 4b of the shaft member 4 and the other end contacts with one blade body 2 so that both the blade bodies 2 are sandwiched between a head part 5b of the shaft member 5 and the coil spring via energization force. The head part 4b comprises a disk part 4c extending outwardly in a radial direction from a base end of the shaft part 4a and an annular extension part 4d which extends to the one blade body 2 side from an outer peripheral edge of the disk part 4c with the extending end thereof in contact with the one blade body 2 so as to form a housing space S1 for housing the coil spring 6 between the shaft part 4a and itself. The shaft member 4 is a one-piece machined article.SELECTED DRAWING: Figure 2
