Patent ID: 7943043

Claim:
A magnetic field forming device for active water, which has a fluid flow path formed in a through hole, comprising: a rod-shaped magnet disposed with predetermined spacing with respect to an inner wall of the through hole and having the fluid flow path formed between the inner wall and a side of the magnet; a guide member that is adhered to and fixed to one end or both ends of the magnet and is inserted into an interior of the through hole; and a communication portion formed in the guide member and communicating with the fluid flow path; wherein the through hole extends in an axial direction from one end to another end and has an axial center line, wherein a widest part of the guide member in a direction which is perpendicular to the axial direction is smaller than an opening portion at the one end of the through hole, wherein the guide member has an inclined portion which is inclined relative to the center line such that portions of the inclined portion which are located closer to the magnet are provided closer to the center line than portions of the inclined portion which are located farther away from the magnet, wherein the inclined portion of the guide member is defined by a plurality of inclined portions which are inclined relative to the center line such that portions of the inclined portions which are located closer to the magnet are provided closer to the center line than portions of the inclined portions which are located farther away from the magnet, wherein the inclined portions protrude from an outer perimeter of a base portion in a direction which is perpendicular to the axial direction so as to form a radial or cross shape, and wherein the communication portion is formed in spacing between adjacent inclined portions and the inner wall of the through hole.
