The same parts as those of the conventional structure described above will be described with the same reference numerals. The steam sterilizer 1a includes a horizontal sterilized container 3 with a bottom and which is made of metal and is fixed in the casing 2. On the front surface of the casing 2, one side of the opening 4 of the sterilization container 3 (left side of FIGS. 2 and 3), the sterilization container 3
A metal support bracket 7 is fixedly mounted so as to project forward from the front edge of the. The support bracket 7 is for pivotally supporting a base end portion (a left end portion in FIG. 3) of a swing arm 9 described below, and is configured as follows, for example. That is, as shown in FIGS. 3 and 4, a fixed portion 11 fixed to the front surface of the casing 2 and a pair of parallel support arm portions 12 and 12 protruding forward from both upper and lower ends of the fixed portion 11. Is formed in a U shape. Through holes 13 and 13 extending in the vertical direction are provided at positions where the pair of support arm portions 12 and 12 are aligned with each other, and these through holes 13 and 13 are provided.
It is supported so that the axis 14 is hung over.

A base end portion (left end portion in FIG. 3) of a swing arm 9 made of a metal material is pivotally supported on the pivot shaft 14. That is, the swing arm 9 has a thickness dimension t ₂ that is smaller than the distance t ₁ between the surfaces of the pair of support arm portions 12, 12 that face each other. A through hole 15 having a diameter substantially equal to that of the through holes 13, 13 is formed in the vertical direction. A lid body 6 that can open and close the opening 4 is provided on a portion of the swing arm 9 that faces the opening 4 on one surface (the left surface in FIG. 4).
It is supported and fixed by a conventionally known supporting means such as a bolt. The lid 6 made of a metal material is provided with a sealing portion 16 (packing) on the inner side surface, which is in close contact with the peripheral portion of the opening 4.
Mounting brackets 17, 17 for supporting the cover 10 are fixed to the outer side surface. The cover 10 made of a heat insulating material is supported on the outer surface of the lid body 6 through the mounting brackets 17 and 17 to adjust the appearance of the steam sterilizer 1a. Because of this configuration, the cover 1
