The oil retaining wall 35 can be put in and put out via a bottom face opening 32 of the frame 31. Oils and fats leaked from an apparatus mounted on the frame 31 can be dripped inside of the oil retaining wall 35 via a communication port 33 that is provided on a top face 34 of the frame 31. In a gap W between a sidewall 311 of the frame 31 and a sidewall 351 of the oil retaining wall 35, an upper part of a portion in which the leaked oil from the mounted apparatus can be infiltrated is covered by a guide plate 36 protruding downwards from the sidewall 311 of the frame 31 onto an opening 353 of the oil retaining wall 35. The leaked oil is guided to the inside of the oil retaining wall 35 and the leaked oil is prevented from being infiltrated to the gap W.SELECTED DRAWING: Figure 4
