    • A valve mechanism (24), which constitutes a solenoid valve (10) as one example of a valve, includes a valve plug (58) that is displaced in an axial direction under an excitation action of a solenoid unit (22), and is equipped with a flexible diaphragm (60) disposed between a valve body (16) and an annular groove (78) formed on the outer circumferential surface of the valve plug (58). The diaphragm (60) is flexible accompanied by displacement of the valve plug (58) and includes first through third projections (92, 94, 96) on an inner edge portion (88) thereof. In addition, the first through third projections (92, 94, 96) are capable of coming into touch, respectively, with an inner circumferential surface (80), a first wall surface (82), and a second wall surface (84) of the annular groove (78). Further, the inner edge portion (88) is inserted in the interior of the annular groove (78) while being movable slightly in the direction of displacement of the valve plug (58).
    • 构成作为阀的一个例子的电磁阀(10)的阀机构(24)包括在螺线管单元(22)的励磁作用下沿轴向位移的阀塞(58),并且是 配备有设置在阀体(16)和形成在阀塞(58)的外周面上的环形槽(78)之间的柔性隔膜(60)。 隔膜(60)具有柔性,伴随着阀塞(58)的位移,并且包括在其内边缘部分(88)上的第一至第三突起(92,94,96)。 另外,第一至第三突出部92,94,96分别能够与内圆周表面80,第一壁面82和第二壁表面84接触, 环形槽(78)。 此外,内边缘部88被插入到环状槽78的内部,同时能够沿阀塞58移动的方向稍微移动。
