    摘要: An upwardly inclined connecting surface (23E) is provided on a flange portion (23C) of an upstream cylinder (22), an upwardly inclined connecting surface (28E) is provided on a flange portion (28C) of a downstream cylinder (27), a downwardly inclined connecting surface (32F) is provided on an upstream side flange portion (32B) of a filter accommodating cylinder (31), and a downwardly inclined connecting surface (32G) is provided on a downstream side flange portion (32C) thereof. In consequence, a substantially V-shaped insertion space (S) which is gradually enlarged from a lower side to an upper side can be formed between the upstream cylinder (22) and the downstream cylinder (27). Hence, a space for mounting and removing the filter accommodating cylinder (31) can be formed between the upstream cylinder (22) and the downstream cylinder (27). As a result, the filter accommodating cylinder (31) can be easily mounted to and removed from the upstream cylinder (22) and the downstream cylinder (27).
