Claim Text:
1. A substrate storing container comprising: a container body for storing substrates; a door that is fitted to an opening of the container body; and a locking mechanism for locking the door fitted to the opening of the container body, wherein the locking mechanism includes a rotary driver that is operated from an outside of the door and a locking bar that slides as the rotary driver rotates to bring a distal end into and out of a locking hollow in an inner periphery of the opening of the container body, the rotary driver has a three-dimensional cam to support the locking bar in a swayable manner, the three-dimensional cam has first and second three-dimensional cam portions which are opposite to each other and made apart with an approximately constant gap regarding a thickness direction of the door therebetween, the locking bar is held by the gap, when the door is locked, the rotary driver is rotated in a locking direction to cause the first and second three-dimensional cam portions to follow the locking bar so as to project the distal end of the locking bar out of the door into the locking hollow of the container body in a substantially non-contacting manner and then move the locking bar in the thickness direction of the door, thereby bringing the distal end into contact with a wall surface forming the locking hollow, the first three-dimensional cam portion has a first inclined cam surface gradually going toward the thickness direction of the door as the first inclined cam surface goes toward the locking direction, and the second three-dimensional cam portion has a second inclined cam surface gradually going toward the thickness direction of the door as the second inclined cam surface goes toward the locking direction.
