1. A dampening water spraying device for a dampening arrangement for spraying dampening water from a nozzle onto a printing plate surface or onto a peripheral surface of a roller leading to the printing plate, the spraying device comprising:a nozzle for spraying dampening water;a nozzle holder including, an end surface connectable to said nozzle, and an outer peripheral portion provided with at least one groove; anda nozzle fixing member including, an opening portion adapted to expose at least a spout of said nozzle, and an inner peripheral portion provided with an adjustable nozzle attachment/detachment moving portion opposed to and engageable with said groove, said nozzle fixing member being adapted to be fastened to said nozzle holder while clamping said nozzle between said nozzle fixing member and said nozzle holder;wherein said nozzle fixing member includes an outer peripheral portion provided with a handhold portion for making it possible to manually rotate said nozzle fixing member; andwherein said nozzle fixing member is capable of fixing said nozzle to said nozzle holder by manually rotating said nozzle fixing member in one direction relative to said nozzle holder, and is capable of detaching said nozzle from said nozzle holder by manually rotating said nozzle fixing member in the other direction relative to said nozzle holder.2. A dampening water spraying device for a dampening arrangement for spraying dampening water from a nozzle onto a printing plate surface or onto a peripheral surface of a roller leading to the printing plate, the spraying device comprising:a nozzle for spraying dampening water;a nozzle holder including, an end surface connectable to said nozzle, and an outer peripheral portion having at least one adjustable nozzle attachment/detachment moving portion; anda nozzle fixing member including, an opening portion adapted to expose at least a spout of said nozzle, and an inner peripheral portion provided with a groove opposed to and engageable with said nozzle attachment/detachment moving portion, said nozzle fixing member being adapted to be fastened to said nozzle holder while clamping said nozzle between said nozzle fixing member and said nozzle holder;wherein said nozzle fixing member includes an outer peripheral portion provided with a handhold portion for making it possible to manually rotate said nozzle fixing member; andwherein said nozzle fixing member is capable of fixing said nozzle to said nozzle holder by manually rotating said nozzle fixing member in one direction relative to said nozzle holder, and is capable of detaching said nozzle from said nozzle holder by manually rotating said nozzle fixing member in the other direction relative to said nozzle holder.3. The dampening water spraying device of claim 1 or 2,wherein said nozzle attachment/detachment moving portion is a protruded body, andwherein said groove to be engaged with said nozzle attachment/detachment moving portion is a helical groove shorter than the circumference of a peripheral portion to be provided with said helical groove.4. The dampening water spraying device of claim 1 or 2,wherein said nozzle attachment/detachment moving portion and said groove to be engaged with said nozzle attachment/detachment moving portion are threaded members, respectively.5. The dampening water spraying device of claim 1 or 2,wherein said opening portion of said nozzle fixing member has a shape formed to enable said nozzle to pass through said opening portion when said opening portion and said nozzle are placed in a predetermined phase relationship.6. The dampening water spraying device of claim 1 or 2,wherein said nozzle is incorporated in said nozzle fixing member in a manner to be allowed to move relative to said nozzle fixing member, and to be prevented from separating from said nozzle fixing member.7. The dampening water spraying device of claim 1 or 2,wherein said outer peripheral portion of said nozzle holder comprises a cylindrical member provided integrally with said nozzle holder.8. The dampening water spraying device of claim 1 or 2,wherein said inner peripheral portion of said nozzle fixing member comprises a cylindrical member provided integrally with said nozzle fixing member.9. The dampening water spraying device of claim 1 or 2,wherein said handhold portion comprises at least one projected portion projected from said outer peripheral portion of said nozzle fixing member.10. A dampening water spraying device for a dampening arrangement for spraying dampening water from a nozzle onto a printing plate surface or onto a peripheral surface of a roller leading to the printing plate, the spraying device comprising:a nozzle for spraying dampening water;a nozzle holder including, an end surface connectable to said nozzle, and an outer peripheral portion provided with at least one groove;a nozzle fixing member including, an opening portion adapted to expose at least a spout of said nozzle, and an inner peripheral portion provided with a nozzle attachment/detachment moving portion opposed to and engageable with said groove, said nozzle fixing member being adapted to be fastened to said nozzle holder while clamping said nozzle between said nozzle fixing member and said nozzle holder; andpositioning means capable of fixingly restricting an attached relationship of said nozzle relative to said nozzle holder;wherein said nozzle fixing member includes an outer peripheral portion provided with a handhold portion for making it possible to manually rotate said nozzle fixing member; andwherein said nozzle fixing member is capable of fixing said nozzle to said nozzle holder by manually rotating said nozzle fixing member in one direction relative to said nozzle holder, and is capable of detaching said nozzle from said nozzle holder by manually rotating said nozzle fixing member in the other direction relative to said nozzle holder.11. A dampening water spraying device for a dampening arrangement for spraying dampening water from a nozzle onto a printing plate surface or onto a peripheral surface of a roller leading to the printing plate, the spraying device comprising:a nozzle for spraying dampening water;a nozzle holder including, an end surface connectable to said nozzle, and an outer peripheral portion having at least one nozzle attachment/detachment moving portion;a nozzle fixing member including, an opening portion adapted to expose at least a spout of said nozzle, and an inner peripheral portion provided with a groove opposed to and engageable with said nozzle attachment/detachment moving portion, said nozzle fixing member being adapted to be fastened to said nozzle holder while clamping said nozzle between said nozzle fixing member and said nozzle holder; andpositioning means capable of fixingly restricting an attached relationship of said nozzle relative to said nozzle holder;wherein said nozzle fixing member includes an outer peripheral portion provided with a handhold portion for making it possible to manually rotate said nozzle fixing member; andwherein said nozzle fixing member is capable of fixing said nozzle to said nozzle holder by manually rotating said nozzle fixing member in one direction relative to said nozzle holder, and is capable of detaching said nozzle from said nozzle holder by manually rotating said nozzle fixing member in the other direction relative to said nozzle holder.
