To provide a storage device with a door having a storage shelf and a temporary placing shelf function and having a simple structure and good usability.

This storage device 1 with a door includes: a storage body 10; a shelf body 20 stored in the storage body 10; a door 30 closing a front surface of the storage body 10 in a closed state; and an arm body 40a interlocking the shelf body 20 with the door 30. The arm body 40a is rotatably connected to the shelf body 20 via a pin 58, and a second part 42 thereof is engaged with a first guide groove 17 formed at a side surface 11a of the storage body 10 via a roller 44. The first guide groove 17 is formed in a curved shape so that its lowermost end is positioned below a lowermost end of a circular-arc virtual groove about the pin 58 with a common uppermost end. Accordingly, the position of the pin 58 in an open state is lower than that of the closed state indicated by a chain double-dashed line. Since the shelf body 20 moves downward with the movement to the open state, the operation such as storage into the shelf body 20 is facilitated to improve usability.
