  • the jet disk is held both in its central region and in its peripheral region on the main body of the shower head, which increases the stability of the support of the jet disk on the base body compared to only a central attachment or only peripheral attachment.
  • This can be particularly beneficial for shower heads with comparatively large-area jet disk and / or shower heads, which are operated with relatively high water pressures.
  • the jet disk attachment to the base body requires no different assembly operations due to the special design of the holding means. Rather, the jet disk attachment takes place in a single assembly process by which both the central holding means and the peripheral holding means are brought together in their respective holding position.
  • the jet disk holding device has a securing lock, which secures against disassembly of the jet disk from the main body. This prevents the jet disc from unintentionally detaching from the base body or being unauthorizedly disassembled from it.
  • the first holding means and / or the second holding means are designed as a bayonet mount or screw holder or clip holder. This represents structurally simple and functionally reliable attachment alternatives for the jet disk on the base body.
  • both holding means are designed as bayonet mounting or screw holder or clip holder and thus of the same fastening type. This can simplify manufacture and / or assembly.
  • the first and / or the second holding means include a jet-disk-side holding element on the jet disk and a cooperating with this, housing-side retaining element on the base body.
  • the former can keep the component costs low, the latter can be useful, for example, in applications in which the intermediate plate fulfills a further function, for example as a distributor plate, in order to be able to direct water supplied into the shower head into different discharge chambers in front of the jet disk.
  • the safety lock comprises a locking pin receptacle on the jet disk and a locking pin held on the shower head body, which can be received in the locking pin receptacle in a disassembling manner.
