Parts, such as sensors, filters, and so forth are extended by means of the auxiliary member. The aforementioned parts attaching grooves are constructed such that a lower side groove wall is slanting in a gradually outside-down manner toward a groove opening side, and further the auxiliary member includes a projection edge for latching, at a tip end of left and right side walls, and the auxiliary member is attached to the aforementioned ionizer main body by means of elastically latching the projection edge to the aforementioned parts-attaching groove. ## Claims ### Claim 1 An ionizer with parts-extension unit comprising: an ionizer main body including, a laterally long housing including, a lower surface where an electrode-attaching opening is opened, and side surfaces both continuing into the lower surface, an electrode for generating an ion, attached in the electrode-attaching opening, and a pair of parts-attaching grooves extending in a longitudinal direction of the housing at a position situated nearer a lower end portion of both of the side surfaces of the housing; and an auxiliary member for extending parts, attached to the ionizer main body by means of latching the same to the parts-attaching grooves, wherein the parts-attaching grooves includes an upper side groove wall and a lower side groove wall, and at least a wall portion of a groove opening side of the lower side groove wall is slanted in a gradually outside-down manner, and wherein the auxiliary member includes a pair of attaching side walls facing to each other, and projection edges for latching is formed at a tip end of the side walls, and wherein the auxiliary member is detachably attached to the ionizer main body by means of elastically latching the projection edges to the parts-attaching grooves. ### Claim 2 (depends on 1) The ionizer according to claim 1, wherein a guide surface for guiding the projection edges to an attaching groove is formed by means of that a wall-height of the lower side groove wall from a groove bottom to a groove opening in the parts-attaching grooves is formed to be lower than a wall-height of the upper side groove wall from a groove bottom to a groove opening, and that a surface of the lower side groove wall extending from a groove opening end to the lower surface is slanted in a direction gradually approaching a center of the housing. ### Claim 3 (depends on 1) The ionizer according to claim 1, wherein an angle formed by a slanting wall portion of the lower side wall at the parts-attaching grooves and a virtual vertical surface (M) that divides the housing into two at a center of a width direction is from about 10 to about 80 degrees. ### Claim 4 (depends on 2) The ionizer according to claim 2, wherein an angle formed by a slanting wall portion of the lower side wall at the parts-attaching grooves and a virtual vertical surface (M) that divides the housing into two at a center of a width direction is from about 10 to about 80 degrees. ### Claim 5 (depends on 1) The ionizer according to claim 1, wherein the auxiliary member serves as a drop-off prevention cover for holding the electrode so as not to drop off from the electrode-attaching opening. ### Claim 6 (depends on 2) The ionizer according to claim 2, wherein the auxiliary member serves as a drop-off prevention cover for holding the electrode so as not to drop off from the electrode-attaching opening. ### Claim 7 (depends on 3) The ionizer according to claim 3, wherein the auxiliary member serves as a drop-off prevention cover for holding the electrode so as not to drop off from the electrode-attaching opening. ### Claim 8 (depends on 5) The ionizer according to claim 5, wherein the auxiliary member serves as a filter holder for attaching a spongy filter to the electrode-attaching opening. ### Claim 9 (depends on 6) The ionizer according to claim 6, wherein the auxiliary member serves as a filter holder for attaching a spongy filter to the electrode-attaching opening. ### Claim 10 (depends on 7) The ionizer according to claim 7, wherein the auxiliary member serves as a filter holder for attaching a spongy filter to the electrode-attaching opening. ### Claim 11 (depends on 1) The ionizer according to claim 1, wherein the auxiliary member serves as a sensor holder for attaching a sensor for measuring ion balance. ### Claim 12 (depends on 2) The ionizer according to claim 2, wherein the auxiliary member serves as a sensor holder for attaching a sensor for measuring ion balance. ### Claim 13 (depends on 3) The ionizer according to claim 3, wherein the auxiliary member serves as a sensor holder for attaching a sensor for measuring ion balance.
