Fuel injection valve body for direct injection type internal combustion engine

In a fuel injection valve body for a direct injection type internal combustion engine, an entire nozzle body tip portion (3a) is formed in a conical shape protruding from a nozzle body outer peripheral surface (3b) covered with a cap (24). Therefore, neither a corner portion nor a recessed portion is formed on a surface of the nozzle body tip portion (3a). This prevents heat generated by combustion from concentrating at a corner portion or a surface area or from enlarging by a recessed portion, which in turn prevents heat generated by combustion from increasing the temperature of the nozzle body tip portion (3a). Moreover, since a foremost portion (3c) of a spherical shape is formed such that it does not form a corner portion or a recessed portion in a peripheral portion of a conical shape, heat generated by combustion does not increase the temperature of the nozzle body tip portion (3a). The temperature of a nozzle hole can therefore be prevented from increasing and accumulation of deposits can be restricted.
