PURPOSE: To obtain storage capacity without changing the height of a gate post in a gate post type locker, in which the locker for storing a house delivery package is installed at the gate post.

CONSTITUTION: A gate post type locker 1 is mounted so that the section of a storage section 43 is buried in the ground. When a house delivery package is not stored only in storage sections 41, 42, storage capacity is increased when a parting plate 32 is rotated and brought to a vertical state and the storage sections 42 and 43 are communicated, and even the long-sized house delivery package can also be stored. Since the storage section 43 is placed under the ground, storage capacity can be improved without heightening the whole gate post type locker 1.
