Claims

[Scope of Claim for Utility Model Registration] A case locking device for holding an upper case in an open state, which is supported by the lower case so as to be rotatably openable and closable about a case fulcrum, with respect to the upper case and the lower case. a receiving portion provided on one of the upper case and the lower case, and a locking member that is rotatably supported on the other of the upper case and the lower case and engages with the receiving portion when the upper case is opened. a locking member that is removably engaged; and a biasing means that biases the locking member in a direction opposite to a rotational direction of the receiving portion relative to the locking member when the upper case is opened, and the locking member fulcrum portion is located outside the trajectory of the receiving portion, the locking member is made of an elastic body, and
a locking portion that is in a natural state and is positioned from within the trajectory of the receiving portion to outside the trajectory as the locking member rotates;
a rotation restricting portion that prevents the locking member from rotating relative to the receiving portion against the urging of the urging means when the locking portion is located closer to the urging direction of the urging means than the receiving portion; What is claimed is: 1. A case locking device, characterized in that it integrally has a case locking device.
