In a canister, an activated charcoal layer is placed in a fluid passage by which an air intake port is connected to a charge port or purge port, and a chamber dividing the charcoal layer into sections so as to traverse the fuel passage is defined by a grid and a filter pad placed on the surface of the grid. The grid has apertures uniformly formed on the surface of the grid contacting with the filter pad, so as to communicate with the chamber. Formation of the apertures on the surface of the grid prevents the filter pad from coming into the mesh of the grid, thus maintaining flatness of the filter pad.

Canister

A canister for treating evaporated fuel includes a casing which is provided with a fuel vapor inlet, a purge port and a port communicating with atmosphere and in which an adsorbent is accommodated, an air passage disposed inside the casing so as to communicate with the atmosphere communication port, the air passage having a shape for flowing the sucked air in a zigzag manner in the casing, and a filter element arranged between the air passage and the adsorbent disposed inside the casing.
