    • An engaging groove (47) with which a gasket (42) is engaged is provided in each of a front side projecting portion (44) and a rear side projecting portion (46) formed in a filter accommodating cylinder (37) to be positioned on an outer peripheral surface (44A, 46A) of each projecting portion (44, 46). Therefore, when the gasket (42) latches on each of the projecting portion (44; 46) to be fitted thereon from an outside, the gasket (42) can be engaged with the engaging groove (47) provided in each of the projecting portions (44, 46). In consequence, at the time of mounting and removing the filter accommodating cylinder (37), the falling-off of the gasket (42) can be prevented, and, for example, an inspection operation, a cleaning operation and the like of an accommodated particulate matter removing filter (41) can be easily performed.
    • 在形成在过滤器容纳筒(37)中的前侧突出部(44)和后侧突出部(46)中的每一个中设置有与垫圈(42)接合的接合槽(47),以定位在 每个突出部分(44,46)的外周表面(44A,46A)。 因此,当垫圈(42)从外部闩锁在每个突出部分(44; 46)上时,垫圈(42)可与设置在每个突出部分中的接合槽(47)接合 (44,46)。 因此,在安装和移除过滤器容纳筒(37)时,可以防止垫圈(42)的脱落,并且例如可以防止容纳的过滤器的检查操作,清洁操作等 可以容易地进行颗粒物去除过滤器(41)。
