| 摘要 |
An aspect of the invention is an opening-and-closing mechanism including: an opening-and-closing member that open-and-closes an body; a holding member rotatably coupled to the body; a sliding member disposed slidable to the holding member along a longitudinal-direction of the holding member, whose end portion is coupled to the opening-and-closing member, and sliding to the holding member in accompaniment with rotation of the opening-and-closing member; a braking member of an elastic material whose coefficient of friction with one of the sliding member or the holding member is larger than that between the other of the sliding member or the holding member and the one, the braking member sliding to the one in accompaniment with the sliding member sliding to the holding member to generate a braking-force by a frictional-force; and a pressing member disposed on the other, the braking member being mounted thereat, pressing the braking member against the one.
