Abstract
A powder passage component includes a first passage defining unit, a second passage defining unit, and a sealing section. The first passage defining unit has at least a first connecting opening which is formed at a part thereof and which has a first peripheral edge. The first passage defining unit defines a passage space which allows powder to pass therethrough. The second passage defining unit has a second connecting opening having a second peripheral edge, is connected to the first connecting opening of the first passage defining unit at the second connecting opening, and defines a passage space which allows the powder to pass therethrough. The sealing section seals the first peripheral edge and the second peripheral edge. The sealing section includes a liquid gasket. The sealing section has a groove that has a bottom portion and a side facing the corresponding passage space. The groove is formed along one of the first peripheral edge and the second peripheral edge. The liquid gasket is applied to an inside of the groove and elastically deformed so as to be brought into contact with another of the first peripheral edge and the second peripheral edge facing the groove. The sealing section has at least one escape groove that is provided at the bottom portion of the groove or along the other of the first peripheral edge and the second peripheral edge facing the groove. The at least one escape groove allows a part of an elastically deformed portion of the liquid gasket to escape so as not to allow the liquid gasket to extend past at least the side of the groove facing the corresponding passage space.
