    • An acceleration sensor includes a tubular casing having one open end closed by a lid of an elastic material. An magnetic member is received within a sealed space defined by the casing and the lid, and a damper liquid fills in the sealed space. The lid is fixedly connected at its outer peripheral portion to one end portion of the casing including the open end thereof. The lid is deformable away from the other end of the casing so as to absorb a thermal expansion of the damper liquid. The lid has an annular deformable diaphragm portion extending between a central tubular portion of the lid and the outer peripheral portion of the lid. For attaching the lid to the casing, the outer peripheral portion of the lid is pressed into the one end portion of the casing so as to bring the diaphragm portion into contact with the damper liquid, so that part of the damper liquid flows into the tubular portion. Subsequently, an axial bore of the tubular portion is closed by a closure member.
    • 一种加速度传感器包括一个管状壳体,一个开放端由弹性材料的盖子封闭。 磁性构件容纳在由壳体和盖子限定的密封空间内,并且阻尼液填充在密封空间中。 该盖在其外周部固定地连接到包括其开口端的壳体的一个端部。 盖子可以远离壳体的另一端变形,以吸收阻尼液体的热膨胀。 盖具有在盖的中央管状部分和盖的外周部分之间延伸的环形可变形膜部分。 为了将盖子附接到壳体,盖的外周部被压入壳体的一个端部,以使隔膜部分与阻尼液接触,使得阻尼液的一部分流入管状 一部分。 随后,管状部分的轴向孔被封闭构件封闭。
