AI Technical Summary
Technical Problem
The abutting sound between the tip of the rod and the locking recess during the closure of the lid body is annoying due to the rod's advancement and retreat against the biasing means.
Method used
A locking device with a retraction mechanism that pulls the locking member in the retraction direction against the biasing force as the lid member moves toward the closed position, and releases the retraction at the closed position, preventing contact with the locking recess.
Benefits of technology
The noise level during closure is reduced, and the lid member is securely locked without any tapping sounds, enhancing the quietness and marketability of the storage device.

Abstract
The present invention provides a locking device that can improve the quietness of closing the opening with a lid member, and a storage device equipped therewith. [Solution] The locking device 1 includes a rod 10 that is positioned to move forward and backward in either the main body 5 or the lid member 6, and switches between locking and unlocking in response to insertion and removal as the rod moves forward and backward in a locking recess 15 formed in the other of the main body 5 and the lid member 6; a biasing means 21 that biases the rod 10 in the forward direction; and a retraction mechanism 12 that pulls the rod 10 in the retraction direction against the biasing of the biasing means 21 as the lid member 6 moves toward the closed position relative to the main body 5, and releases the retraction of the rod 10 in the retraction direction when the lid member 6 is in the closed position.
