摘要： A fuel injection valve includes a nozzle, a housing, a needle, and a throttle portion. The nozzle includes an injection hole through which fuel is injected and a valve seat formed around the injection hole. The nozzle includes an injection hole through which fuel is injected and a valve seat formed around the injection hole. The housing has a fuel flow path through which the fuel to the injection hole flows. One end of the needle is configured to open and close the injection hole by being separated from the valve seat or abutted on the valve seat. The throttle portion is provided upstream with respect to the valve seat in a fuel flow direction.

摘要： A spark plug 5 for an internal combustion engine includes a center electrode 1, an insulator 2, and a housing 3. The insulator 2 includes a distal end side exposed part and an insulator enlarged diameter part 21. The housing 3 includes a lateral electrode 32, an engaging part 33, and a crimping portion 35. A buffer member 4 that restrains the distal end side exposed part 20 by pressing a part of the distal end side exposed part 20 toward the center and a part of the inner peripheral surface of the lateral electrode 32 in a radial direction at a distal end side of the engaging part 33 is disposed at a base end side of the gas pocket 230.
