Claims

[Scope of utility model registration request]

In a filter unit in which the opening surface of a filter case in which a filter element is built-in is closed with a bracket, a band is formed by rotatably connecting a plurality of connecting pieces and surrounds a fitting portion between the filter case and the bracket. and forming opposing pieces protruding radially outward at both ends of the band that face each other at a portion of the outer periphery of the fitting part, the opposing pieces including a notch hole with one end open toward the outside. A concave surface is formed on the back side of the opposing piece to form a hole, and the opposing pieces are closest to each other on the axis of the bolt inserted into the mounting hole, and a convex surface that abuts the concave surface of the opposing piece, respectively. A filter tightening device comprising: a spacer screwed onto the head side of the bolt; and a nut screwed onto the front end side of the bolt.
