知られている。 An air cleaner element having an adsorbent for evaporated fuel is placed inside the air cleaner case, and the adsorbent adsorbs evaporated gasoline from the carburetor, etc. to the clean side of the air cleaner connected to the engine intake system. There is a known vaporized fuel adsorption device that prevents vaporized fuel from flowing into the atmosphere and prevents vaporized gasoline from filling the clean side of the air cleaner when the engine is restarted at a high temperature, resulting in over-richness and difficulty in starting. ing.

の収納スペースの効率的利用をも図れる。 An air cleaner element is also known in which an element having the above-mentioned adsorbent and an element made of ordinary paper are stacked in two layers in parallel in the air inflow direction. Since the adsorbent can sufficiently adsorb evaporated gasoline while maintaining a high airflow resistance with the paper, it is possible to prevent pollution, improve the high-temperature restartability of the engine, and improve the durability of the air cleaner element as a whole. It also allows efficient use of internal storage space.

つて一方の耐久限度に応じて両方のエレメントを
ともに交換しなければならないため、メンテナン
スにおけるコストアツプを招いていた。 However, because the paper element and the adsorbent element have different functions, their durability differs, and both elements must be replaced at the same time depending on the durability limit of one, leading to increased maintenance costs. .

Since there is a risk that foreign matter such as dust may enter the clean side from the side through the gap, consideration must be given to measures to prevent this.

ある。 The present invention was developed in response to the above demands and countermeasures, and its purpose is to allow both elements in two parallel stages to be attached and detached from each other with a single touch, and therefore to be replaced separately depending on the durability of each element. This reduces maintenance costs and
Moreover, it is an object of the present invention to provide an evaporated fuel adsorption device for an air cleaner that prevents the generation of a gap between the contact surfaces of both elements and prevents the intrusion of foreign matter such as dust.

The fine particles are first sieved by the coarse mesh of the coarse filter 25, and then the fine particles are sieved by the fine mesh of the fine filter 26, which prevents the fine particles from flowing to the clean side C, similar to the filter to the dirty side. It is possible to maintain a sufficient amount of intake air by the coarse filter 25 and to suppress clogging of the fine filter 26, thereby improving the filter function. It is possible to reduce the influence on the engine intake system.
