PROBLEM TO BE SOLVED: To provide a housing structure at an upper part of a shelf board which enables smooth gliding of a housing body on a rail by minimizing the twisted deformation of the housing body made of a resin and enables installing of a partition body at an arbitrary position so as to obtain a housing space as desired. SOLUTION: In the housing structure at an upper part of a shelf board 12, rail parts 14 and 16 extending horizontally are formed at an upper part of the shelf board 12 and box-shape housing bodies 18 to 24 opened forward and upward are slidably installed on the rail parts 14 and 16. The housing bodies 18 to 24 are made of a resin and groove lines 18c to 24c are formed almost entirely in the bottom surface and the back side on the housing side thereof, extending longitudinally in the bottom surface and vertically in the back side thereof. Partition bodies 28 able to be engaged with the groove lines are provided at proper points of the groove lines 18c to 24c.
