Document Type and Number:
Japanese Patent JP6994301
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an opening/closing mechanism such as a camera diaphragm or a fastening mechanism such as an aperture variable spectacle camera, capable of setting opening and closing ports to optional polygonal shapes in the opening/closing mechanism capable of forming the opening and closing ports as similar shapes so as to be expanded/contracted, and smoothly expanding/contracting and completely closing the opening and closing ports, and a power mechanism such as an engine that generates a rotational force through application of pressure in the opening and closing ports.SOLUTION: In the opening/closing mechanism for expanding/contracting an opening through movement of each of slide bodies, the opening being formed by being enveloped by a slide surface in which slide bodies each having upper and lower surfaces and a plurality of side surfaces are included in a circle and the side surfaces of the slide bodies come into contact with each other, the similar shape forming mechanism is characterized in that for example, by enabling the opening of a spectacle wrench to be adjusted so as to be expanded/contacted by a mechanism capable of expanding/contracting openings to be opened/closed as similar shapes and optionally setting positions during full closing, bolts or nuts different in size are fastened/loosened by a single spectacle wrench.SELECTED DRAWING: Figure 2
