PROBLEM TO BE SOLVED: To provide a cap with less number of parts and a simple structure and a smoothly opening/closing cover. SOLUTION: When pushing a top face 36 of a pushing member 34, the pushing member 34 swings anticlockwise around the center of a rotary axis 40. Thereby, a projection 44 pushes the lower end of a rising wall 32 and a rotary moment generates around the shaft hole 28 of the cover 20 to open the cover 20. And further, when pushing the top face 36 of the pushing member 34, the projection 44 slips out of the lower end of the rising wall 32 and the rib 46 is pushed in the groove between claws 50 to fully open the cover 22. On closing the cover 22, the cover 20 is directly pushed by fingers. Then the rib 46 pushes back the groove between claws 50 to the position the projection 44 contacts the rising wall 32 in the interlocking motion with the above movement. Subsequently, the rising wall 32 pushes back the projection 44 and the pushing member 34 swings and returns to the initial position. |
