摘要： An electric generator 1 includes a shaft 3a (metal rotating body), a ball bearing 4 (metal holding body) configured to hold the shaft 3a, and a resin spacer 5 (resin member) used together with these components. A resin part included in the spacer 5 includes reinforcement fibers F pointing in random directions in a plane orthogonal to the axial direction of the shaft 3a. The linear expansion coefficient of the resin part in a direction orthogonal to the axial direction is the same as the linear expansion coefficient of a metal part included in the shaft 3a or the ball bearing 4. Accordingly, the resin member that achieves a dimensional stability can be provided.

摘要： In a metallic gasket having a metallic sheet made with a recess surrounding around a diverse type of hole, in which an elastic sealing member is installed, a relation between the recess and the elastic sealing member in their cross sections and also configurations is so specified as to use the elastic sealing member within a range of elastic limit inherent in the elastic sealing member, thereby improving the sealing performance of the metallic gasket. The elastic sealing member installed in the recess formed around the hole such as combustion hole and so on is composed of a top extending above a major side of the metallic sheet, and a bottom having a cross section reaching widthwise opposing side surfaces of the recess. The elastic sealing member is made not more than the recess in their cross section perpendicular to the major side of the metallic sheet. Thus, the elastic sealing member, when the metallic gasket is squeezed, may serve its useful function within the range of inherent elastic limit. This helps ensure the properly tight and enduring sealing condition, thereby keeping the gasket against premature degradation and any collapse.
摘要翻译：在具有金属片的金属制垫片中，该金属片具有围绕各种类型的孔围绕的凹部，其中安装有弹性密封构件，凹部和弹性密封构件之间的横截面和构造的关系如在弹性密封构件固有的弹性极限范围内使用弹性密封构件，从而提高金属衬垫的密封性能。安装在诸如燃烧孔等的孔周围形成的凹部中的弹性密封构件由在金属片的主侧上方延伸的顶部以及具有横截面的宽度方向相对的侧面的底部构成。弹性密封构件在垂直于金属片的主侧的横截面中不大于凹部。因此，当金属垫圈被挤压时，弹性密封件可以在固有弹性极限的范围内起作用。这有助于确保适当紧密且持久的密封条件，从而保持垫圈免于过早降解和任何塌陷。

摘要： A cylinder head gasket 1 includes at least two first and second seal plates 11 and 12 in which oil drop holes 4 are perforated, respectively. On the first and second seal plates, half beads 11a and 12a that endlessly surround the oil drop holes and that project in a direction toward each other to be mutually pressed are formed, and the oil drop holes are sealed by these half beads. Outside of the respective half beads, auxiliary beads 11c and 12c that project in a direction toward each other to be mutually pressed are formed. Projection directions of the half beads and the auxiliary beads may be opposite to each other. Since the respective auxiliary beads 11c and 12c give acting forces that press the respective half beads 11a and 12a against a cylinder head or a cylinder block, a better sealing property can be secured as compared with a conventional cylinder head gasket.
摘要翻译：气缸盖垫片1包括至少两个第一密封板11和第二密封板12，在所述第一密封板和第二密封板中分别穿孔有油滴孔4。在第一密封板和第二密封板上形成环绕油滴孔并且沿彼此相向的方向突出以相互挤压的半环11a和12a，并且油滴孔被这些半环密封。在各个半球的外侧，形成有朝相互相向的方向突出并相互压入的辅助突条11c，12c。半珠和辅助珠的投影方向可以彼此相反。由于相应的辅助凸缘11c和12c产生将各个半凸缘11a和12a压靠在气缸盖或气缸体上的作用力，所以与传统的气缸盖垫片相比，可以确保更好的密封性能。

摘要： A gasket-squeeze construction wherein a warp-limiter member(17) is installed in a bolt hole(15) in which a fastening bolt(7) fits. The warp-limiter member(17) is made less in an amount of flex than confronting surfaces(4,5), between which the gasket(1) is disposed and squeezed by the tightening of the fastening bolt(7). The warp-limiter member(17) serves to make the sealing stress uniform around a combustion gas hole. The warp-limiter member(17) installed in the bolt hole(15), because of tougher to flex than the confronting surfaces(4,5) when tightening the fastening bolt(7), makes uniform the clamping force of the fastening bolt(7) and the compressive stress created around the associated bolt hole(15), moreover dispersing uniformly the sealing stress throughout around the combustion gas hole such as a cylinder bore(25), thereby rendering variation in distortion in the sealing joint less to improve the sealing performance.

摘要： A laminated gasket (1) is provided, which ensures desired bore (5) sealing surface pressures on the side of a cylinder head and on the side of a cylinder block, which is excellent in sealing ability and durability preferably by virtue of its double sealing function and which has a comparatively simple structure. This gasket (1) has a core plate (12) and elastic plates (13,14) laminated to both surfaces of the core plate (12). The core plate (12) has thin-walled portions (12a) each surrounding a bore opening (5) and a thick-walled portion extending outwardly from each thin-walled portion. The elastic plates (13,14) respectively have folded-back portions (13b,14b) each of which is formed so as to create, together with a base portion, a clearance around its associated bore opening (5).
