摘要： A metal gasket is designed so that mounting and removal from a cylinder block using a bolt is easy regardless of the direction of the attaching surface and there is no risk of moving or drop off. The gasket is made of two laminated metal base plates. At a base plate part near a bolt hole of one metal base plate, a bolt engaging piece projects so that the diameter of the bolt hole is smaller than the diameter of the bolt for fastening, and an assistant piece for handling is integrated thereto. At the base plate part of the other plate overlapping the assistant piece, a cut recess is formed. When inserting the bolt into the bolt hole of the metal gasket, the bolt engaging piece is struck against the bolt and is elastically bent, and allows the bolt to pass. The gasket mounted on the bolt is kept at the mounting position by the pressing action to the bolt from the impact resilience force of the bolt engaging piece. Furthermore, the metal gasket can easily be removed in such a way that the assistant piece is held with a fingertip or the like and the bolt engaging piece is separated from the screw part of the bolt. The recess of the metal base plate is useful for making the handling of the assistant piece easy.

摘要翻译： 设计金属垫片，使得使用螺栓的气缸体的安装和拆卸容易，而不考虑安装表面的方向，并且不存在移动或脱落的风险。 垫片由两个层压金属基板制成。 在一个金属基板的螺栓孔附近的基板部分处，螺栓接合片突出，使得螺栓孔的直径小于用于紧固的螺栓的直径，并且用于操纵的辅助件被一体化。 在与辅助件重叠的另一个板的基板部分处，形成切口凹部。 当将螺栓插入金属垫圈的螺栓孔中时，螺栓接合件撞击螺栓并弹性弯曲，并允许螺栓通过。 安装在螺栓上的垫圈由螺栓接合件的冲击弹力通过对螺栓的按压作用而保持在安装位置。 此外，金属垫圈可以容易地被移除，使得辅助件用指尖等保持，并且螺栓接合件与螺栓的螺钉部分分离。 金属基板的凹部对于使辅助件的处理变得容易是有用的。
