- the edge of the opening 331a of the cap member 330 is seen when viewed from the axial direction of the nozzle portion 311 in a state where the cap member 330 is fitted on the outer peripheral side of the injection needle mounting portion 313.
- the case where all of these are located inside the valley diameter of the spiral groove 314 provided on the inner peripheral surface of the injection needle mounting portion 313 is illustrated, but the present invention is not limited thereto, and the nozzle insertion portion 240 can be inserted.
- the base end side of the injection needle 400 is configured so as not to be inserted, at least a part of the edge of the opening 331a only needs to be located inside the valley diameter of the spiral groove 314.
- the cap member 330 may be provided with a protruding portion that protrudes radially inward from at least a part of the edge of the opening 331a.
- the guide groove provided on the inner peripheral surface of the injection needle attachment portion 313 is the spiral groove 314
- the present invention is not limited thereto, and the injection needle is attached. As long as it can be configured, it can be changed as appropriate.
