PROBLEM TO BE SOLVED: To provide a packing that is enabled to be efficiently replaced, enabled an amount of burr generated at mating surfaces to be reduced and at the same time enabled burrs to be easily removed.SOLUTION: This invention relates to a packing, a mold for foam molding, and a foam molding method. The packing has a first seal surface and a second seal surface that are oppositely facing to each other in its thickness direction and at the same time has a plate-like seal part, and a fixing part for use in fixing the packing against an object to be used. The second seal surface is formed with a fluid storing groove and a fluid guide groove. The fluid storing groove extends in an extending direction of the packing, and the fluid guide groove is formed at the seal surface at one side in a width direction, passes from one side end surface in a width direction of the packing up to the fluid storing groove. Under the sealed state, the fluid present at one side end surface in the width direction can enter into the fluid storing groove through the fluid guide groove.SELECTED DRAWING: Figure 1 【課題】効率よく交換でき、合わせ面に発生するバリが少なくなるとともにバリが除去されやすいパッキンを提供する。【解決手段】本発明は、パッキン、発泡成形用金型及び発泡成形方法に関するものである。パッキンは、厚み方向において対向している第１シール面と第２シール面とを有するとともに、板状をなすシール部と、前記パッキンを使用対象に取り付けるための取付部と、を備え、前記第２シール面には、流体貯留溝と流体案内溝が形成されており、当該流体貯留溝は、前記パッキンの延伸方向に延びており、当該流体案内溝は、幅方向一方側のシール面に形成され、前記パッキンの幅方向一方側の端面から前記流体貯留溝まで貫通し、シール状態では、前記幅方向一方側の端面に存在する流体は、前記流体案内溝を経て前記流体貯留溝に入ることができる。【選択図】図１
