Abstract

A first recess and protrusion engagement portion and a second recess and protrusion engagement portion making a fan guide and one end portion of a leg swingably abut on each other and making a base plate and the other end portion of the leg swingably abut on each other, respectively, and restricting a deviation of the leg relative to the fan guide and the base plate in a horizontal direction while allowing swinging of the leg relative to the fan guide and the base are provided between the fan guide and the one end portion and between the base plate and the other end portion, respectively. The leg can swing with almost no resistance without involving any elastic deformation during the orbital motion of the base, and stress to cause elastic deformation is not applied to the leg unlike the conventional art.
