摘要： A damping valve includes a valve seat member, a first valve element stacked on the valve seat member, a second valve element provided between an inner circumference valve seat of the valve seat member and the first valve element, the second valve element being configured to open and close a hole of the first valve element, and a biasing member configured to bias the first valve element towards the second valve element, wherein a surface of the second valve element on an opposite side from the valve seat member is higher than the outer circumference valve seat of the valve seat member.

摘要： A rod guide includes a housing portion and a depressed portion formed toward an outer periphery from a starting point located apart from a piston rod by ½ or more of a distance in an axial direction between a bottom surface of the housing portion and a flat portion of an oil seal in a radial direction closest to the piston rod, and a bush is disposed to be flush with the bottom surface or disposed to project.

摘要： A solenoid includes a first fixed iron core and a second fixed iron core located on one axial end side and the other axial end side of a coil, a first movable member and a second movable member located between those fixed iron cores and configured to be attracted to the first fixed iron core and the second fixed iron core, respectively, by energization of the coil, a spring configured to bias the first movable member toward the second fixed iron core, and a first regulating portion made from a non-magnetic material, provided integrally with the first movable member or the second movable member, and configured to regulate movement of the first movable member toward the second fixed iron core with respect to the second movable member.

摘要： A solenoid includes a first fixed iron core and a second fixed iron core located on a first end side and a second end side of an axial direction of a coil, a first movable iron core and a second movable iron core located therebetween and attracted by the first fixed iron core and the second fixed iron core by passage of current through the coil, respectively, a spring that biases the first movable iron core to the second fixed iron core side, and a leaf spring that regulates movement of the first movable iron core to the second fixed iron core side with respect to the second movable iron core. The movement of the first movable iron core in a direction orthogonal to the axial direction of the coil with respect to the first fixed iron core and the second fixed iron core is regulated.
