A sound absorbing and insulating member alternately brought into contact with a first partition member and a second partition member. The sound absorbing and insulating member has a plurality of hollow protrusions protruding so as to traverse a gap between the partition members. There is a first and second space between the first and second partition member. The first space is formed in each protrusion and is closed by the first partition member. The second space is provided between adjacent protrusions and is closed by the second partition member. The first and second spaces communicate with each other through a communication part formed as a part of the protrusion. The communication part is configured to communicate an inside of the protrusion with an outside. An opening of the communication part opened to the second space is provided at a side wall of the protrusion.
