PROBLEM TO BE SOLVED: To prevent an unusual noise caused by loosing of a sliding door in a direction orthogonal to a sliding direction thereof. SOLUTION: An elastic member 260 is provided between a side face 26m of the both side faces 26m in the sliding door 26 and the inner wall surface 120a of a case 120 in an elastically deformed state in the direction W orthogonal to the sliding direction (a) of the sliding door 26 by the amount of elastic deformation L4. Thereby, a boss part 26p in the other side face 26m of the both side faces 26m in a door base plate 26a wherein the elastic member 260 is not arranged is pressed on the inner surface 120a of the case 120 by an elastic force of the elastic member 260. The unusual noise caused by loosing of the sliding door 26 in the direction W orthogonal to the sliding direction (a) between it and the case 120.
