A fuel feed pump capable of stably feeding a fuel by preventing a tappet body from being damaged even if the pump is loaded at a high pressure over a long period and a tappet structure suitable for the fuel feed pump. In the fuel feed pump, the tappet structure comprises rollers in contact with cams and tappet bodies having roller storage parts in which the rollers are stored. A pressure regulating member for dispersing a loading force is interposed between the tappet body and a plunger. The pressure regulating member comprises, for example, a recessed part at the center of its surface facing the tappet body, and is brought into contact the tappet body around the recessed part. |
