A container is provided comprising a casing, a set plate closing the lower end of the casing and a lock ring that fastens the set plate onto the casing. The casing is provided with a radial outer flange formed around an open end of the main body thereof. The radial outer flange and the outer periphery of the set plate are each provided with three stop projections and three notches. The radial outer flange is further provided with three biasing projections and the outer periphery of the set plate is further provided with three engagement rims. The members of each threesome are arranged at a regular angular interval and each threesome is arranged at different angular phase positions from those of the other threesomes. The outer periphery of the lock ring is provided with three engagement lugs that project inwardly at a regular angular interval.

Container having a detachable lid

A filter device includes a tubular casing &lsqb; &rsqb; with a closed bottom, a filter element &lsqb; &rsqb; received within the casing &lsqb; &rsqb;, a lid &lsqb; &rsqb; which closes an open end of the casing &lsqb; &rsqb;, and has a communication hole communicating the inside and outside of the casing &lsqb; &rsqb; with each other, and a fastening member &lsqb; &rsqb; fastening the casing &lsqb; &rsqb; and the lid &lsqb; &rsqb; together. A gap is formed between a peripheral wall &lsqb; &rsqb; of the open end portion of the casing &lsqb; &rsqb; and a peripheral surface &lsqb; &rsqb; of that portion of the lid opposed to the peripheral wall &lsqb; &rsqb;. A radial seal width w of an annular elastic seal member &lsqb; &rsqb; to be mounted in the gap is larger than a width d of the gap in the radial direction, and the seal member &lsqb; &rsqb; closes the gap liquid-tight in the radial direction, and the seal member &lsqb; &rsqb; closes the gap liquid-tight in the radial direction when the filter device is assembled. With the filter device, a positive seal therebetween can be achieved, even if a casing and a lid are fastened together somewhat inadequately.

Filter device

A spring is crimpingly fixed to an element holding plate of the fluid filter. Since the spring is crimpingly fixed to the element holding plate a material having a high elastic limit can be freely selected for the spring At the assembling time, the spring can be prevented from yielding to be elastically deformed, even when the size between the upper end of the element and the crest of the filter case fluctuates. As a result, it is possible to provide a fluid filter which requires no high sizing accuracy of the individual parts composing the fluid filter at the assembling time so that it can be easily assembled.

Fluid filter

A valve indicative of the concentration of an emission component contained in exhaust from an internal combustion engine is outputted by an exhaust concentration sensor arranged in the exhaust system of the engine, and the value is compared with a predetermined reference value, followed by obtaining a ratio of a first time period during which the sensor output value exceeds the predetermined reference value to a second time period during which the sensor output value is less than the reference value. The acceptability of the exhaust concentration sensor is determined based on the obtained ratio. Preferably, the sensor is judged to be of acceptable quality when the ratio lies within a predetermined range and defective when the ratio lies outside the predetermined range.
