<p>PROBLEM TO BE SOLVED: To provide a low-cost and easy-to-disassemble air intake and exhaust device having an exhaust passage of a printer body, as an image forming apparatus, and a control unit, without using a double-sided tape or an adhesive for an elastic member in a connectable/separable joint part.SOLUTION: A second joint component 2 is jointed to a first joint component 1. The first joint component 1 has a vent hole 11. The second joint component 2 is cylindrical. A flange part 21 is formed in the second joint component on the side of the first joint component 1. A ring-shaped elastic member 3 is attached to the flange part 21. The elastic member 3 is formed to protrude from an end of the second joint component 2. An inner diameter of the elastic member 3 is set to be smaller than an outer diameter of the second joint component 2. The elastic member 3 is fixed to the second joint component 2 with an elastic force thereof. The elastic member 3 is brought into contact (pressure contact) with a contact part around the vent hole 11 of the first joint component.</p> |
