A lock mechanism is provided with: a lock shaft (12) attached to a first bracket (3); a lock shaft supporting shaft (11); and a pressing spring that presses the lock shaft (12) in the direction in which the lock shaft (12) and the second bracket (4) are brought into contact with each other, restricts the rotation of the first bracket (3) and the second bracket (4) in the locking direction without rattling by bringing the rotation travel restricting stoppers (17, 18) into contact with each other, and sets the lock shaft (12) so that the lock shaft (12) comes into contact with both the first side surface (21) and the second side surface (22), thereby restricting the rotation of the first bracket (3) and the second bracket (4) in the direction in which the rotation travel restricting stoppers (17, 18) are brought into contact with each other. The pair of tangent lines (25, 26) of the locking shaft (12) form a wedge shape (27), so that the rotation of the first bracket (3) and the second bracket (4) in the direction opposite to the locking direction is limited without shaking.
本发明涉及一种锁定机构,具备:锁定轴(12),安装在第1支架(3);锁定轴支承轴(11);弹压弹簧,将锁定轴(12)朝向使锁定轴(12)与第2支架(4)抵接的方向弹压,通过使旋转行进限制挡块(17、18)相互抵接,第1支架(3)及第2支架(4)在锁定的方向上的旋转以没有晃动的方式受到限制,通过设定为使得锁定轴(12)与第1侧面(21)和第2侧面(22)双方接触,且锁定轴(12)的一对切线(25、26)形成楔形(27),从而第1支架(3)及第2支架(4)向与锁定的方向相反方向的旋转以没有晃动的方式受到限制。
