PURPOSE: A unit bearing case is provided to facilitate maintenance by allowing the case to be easily separated from a unit bearing without damage. CONSTITUTION: A unit bearing case comprises a body(120) and a cover(140). The body has a semicircular lower shaft insertion groove(122) and lower junction surfaces(124) formed on the left and right sides of the lower shaft insertion groove. The cover has a semicircular upper shaft insertion groove(142) and upper junction surfaces(146) formed on the left and right sides of the upper shaft insertion groove. The lower and upper shaft insertion grooves have the same diameter. The lower and upper junction surfaces are connected by contacting each other so that the lower and upper shaft insertion grooves form a circular shaft insertion hole in which a shaft is inserted. |
