Claims

[Claims for Utility Model Registration] 1. Both ends of a roller around which a filter is wound are removably and rotatably fitted and supported by a pair of pivot parts provided on the ventilation fan main body, and the filter is attached to the front surface of the ventilation fan main body. The roller is pulled out sequentially from one side to the other side and passed along the front part, and is attached to one of the pair of pivot parts to press the roller toward the other pivot part. A ventilation fan with a filter, characterized in that it is equipped with a ventilation means. 2 The biasing means is constituted by a spring,
A ventilation fan with a filter as set forth in claim 1 of the utility model registration claim, characterized in that the ventilation fan is assembled into a unit together with a receiving plate that abuts the end face of the roller in a receiving member that is attached to one of the pivot parts. .
