A valve timing adjustment device includes a drive-side rotating body that rotates in conjunction with a crankshaft, a driven-side rotating body that rotates integrally with a camshaft, a speed reduction mechanism that transmits rotation while allowing relative rotation between the drive-side rotating body and the driven-side rotating body. The driven-side rotating body includes a fastening portion fastened to the end portion of the camshaft by a center bolt, a bearing portion that is located radially outward of the fastening portion and that axially supports the drive-side rotating body, and a fitting outer surface that is fitted to a regulating member on a side where an outer diameter of an axial contact surface with the other member on one side and the other side in the axial direction of the driven-side rotating body is large.

A fuel injection valve includes a body including a first chamber that supplies fuel of a first pressure, a second chamber that supplies fuel of a second pressure, and an injection hole, a valve chamber member including a valve chamber connectable to the first chamber and the second chamber, a control chamber member including a control chamber connectable to the first chamber, a needle pressed by pressure of fuel in the control chamber in a direction that causes fuel injection from the injection hole to stop, an actuator, a valve element that selectively connects the first chamber, second chamber, and the valve chamber according to the actuator extending and contracting, and a transmission mechanism that when the actuator extends, transmits the force to the needle as a force in a direction that causes fuel to be injected from the injection hole.
