Abstract:
PURPOSE: To facilitate disassembly and assembly by forming a protrusion part on a lower casing and securing a strainer through mutual fastening, in a device wherein upper and lower casings made of resilient material are mounted on an intermediate casing and a strainer is mounted on the side of the lower casing.
CONSTITUTION: A plurality of recessed seats 11 are formed in a strainer 7 and a protrusion part 14 of a lower casing cover 6a is brought into contact with the inner part of the recessed seat 11. A strainer 7, a lower casing 5 (the protrusion part 14 thereof), and an upper casing 4 are secured to an intermediate casing 3 through mutual fastening by means of a plurality of bolts 13 joined in a screwed-in manner to the intermediate casing 3. The bottom part 16, except the protrusion part 14, of the lower casing cover 6a is positioned separately upward of the bottom 18 of the strainer 7. This constitution causes sealing of a portion between the upper and lower casings 4 and 5 by pressing the protrusion part 14 of the lower casing cover 6 and the lower and upper casings 5 and 4 by means of the strainer 7.
