Abstract: A component-mounting device according to an embodiment of the present invention includes a component-mounting board, a connector component, a heat sink, and a first screw portion. The component-mounting board includes a first surface and a second surface opposite to the first surface. The connector component includes a plurality of terminal-fixing portions that fixes a terminal extending in one axis direction orthogonal to the first surface and a base portion that connects between the plurality of terminal-fixing portions and includes an opening portion, the connector component being provided on the first surface. The heat sink faces the second surface and includes a first screw seat that faces the base portion in the one axis direction with the component-mounting board interposed between the first screw seat and the base portion. The first screw portion is disposed inside the opening portion and is engaged with the first screw seat through the component-mounting board.

Abstract: A shock absorber includes a bearing unit having a bearing and a bearing holding member, and a seal unit having a seal member and a seal holding member. The seal holding member includes a seal accommodating portion being configured to accommodate the seal member, and an insertion hole through which a piston rod is inserted. The seal member is pressed against an outer circumferential surface of the piston rod and the seal accommodating portion by working-fluid pressure in the extension-side chamber. And the bearing is provided such that a first end surface of the bearing facing the seal member matches an aperture plane of a through hole of the bearing holding member or such that the first end surface of the bearing projects out from the aperture plane of the through hole.
