Claims

[Scope of utility model registration request]

A drive shaft that is housed and held in a drive shaft case and is rotatable around the axis, and a driven shaft that is housed and held in the driven shaft case and is rotatable around the axis are foldably connected via a universal joint. The drive shaft case and the driven shaft case are refractably connected around the axis of the king pin, and a first bowl-shaped cover having a circular bowl edge is rotated around the axis of the drive shaft while covering the universal joint. A second bowl-shaped cover having a circular bowl edge is held at one end of the driven shaft case so as to be freely rotatable about the axis of the driven shaft while covering the universal joint. The circular bowl edges of the first and second bowl-shaped covers are tilted obliquely with respect to the axis of the king pin and are tightly fitted so as to be rotatable about the bending center of the universal joint, and A guide groove is formed on the top of the second bowl-shaped cover that is parallel to the axis of the drive shaft and is open at least on the driven shaft case side, and a guide groove that is parallel to the axis of the driven shaft is formed on the top of the second bowl-shaped cover. A guide groove is formed which is open on the drive shaft case side, and extends toward the drive shaft case side from the axial center position of the king pin and engages with the guide groove of the first bowl-shaped cover. A mating protrusion is provided on the driven shaft case side, and a protrusion that extends from the axial center position of the king pin toward the driven shaft case side and engages with the guide groove of the second bowl-shaped cover is provided on the drive shaft case side. A universal joint seal cover device characterized by being provided on the shaft case side.
