To solve a problem that conventional rack apparatus in which hoisting and lowering of a rack body is performed by driving force of a motor, impact caused by a sudden stop when a rack is housed into a storing shelf, etc., is large.

A rack body 5 is fitted on the rotating end part of a main arm 16 supported on a rotating shaft 13, so that the rack body 5 can be moved between a housing position where it is housed on a high storing shelf 3 and a taking-out position where it is taken down to this side downward and the rotating shaft 13 is rotated by means of a driving mechanism 30 with a motor 40. Speed of this rotation is made slower when the rack body 5 comes to a position just before housing. For this purpose, a magnetic switch 53 for detecting that the rack body 5 comes to the position just before housing, a transformer T for taking out a 12-volt power source and an 8-volt power source and a relay RX2 for switching two kinds of these power sources and feeding it to the motor 40 are provided.
