Abstract:
1. An insert-molded product comprising: a porous member having opposite first and second surfaces and an outer peripheral surface extending between the opposite first and second surfaces; a first constituent member having a first planar wall with a central opening, the first planar wall engaging an outer peripheral portion of the first surface of the porous member adjacent the outer peripheral surface, the first constituent member further having a first tubular wall extending from the first planar wall and disposed outwardly from the outer peripheral surface of the porous member; a second constituent member having a second planar wall with a central opening, the second planar wall engaging an outer peripheral portion of the second surface of the porous member adjacent the outer peripheral surface, the second constituent member further having a second tubular wall extending from the second planar wall, the second tubular wall being between the outer peripheral surface of the porous member and the first tubular wall and engaging the outer peripheral surface of the porous member; and a molded member insert-molded so that said molded member defines a unitary matrix of resin engaging surfaces of the first and second planar walls opposite the porous member and the outwardly facing surface of the first tubular wall.
