Claims

[Scope of utility model registration request]

This is a lock structure for an opening/closing door that is rotatably supported at one end to open and close, and has locking tools protruding from the upper and lower end surfaces of the door tip of the opening/closing door so as to be retractable, and a base of each locking tool. Rack gears are connected to the end side, and these rack gears face each other so that they can be raised and lowered, and a pinion gear is rotatably provided in mesh with both rack gears, and a horizontal shaft is provided at the tip of the opening/closing door with the axis facing in the thickness direction of the door. An operating handle is provided to be rotatable around a horizontal axis, and one rack gear is pivotally connected to the tip of the operating handle beyond the horizontal axis, and the length from the tip of the operating handle to the horizontal axis is the horizontal axis. This lock structure for an opening/closing door is formed with a receiving surface that is longer than the connection length from the to the rack gear and allows the operating handle to align with the door end face at the upper rotation limit position and the lower rotation limit position of the operation handle.
