The spiral spring is fixed to the housing at an outer end side and locks the lid while being adjacent to the lid at the closing position. The lock operation member includes a shaft member to which an inner end side of the spiral spring is engaged and unlocks the lid by rolling up the spiral spring by the shaft member. The engaging part is provided on a circumferential surface of the lid and engaged to a part of the spiral spring. The spiral spring locks the lid by engaging the engaging part in a large diameter state where the spiral spring is not rolled up by the lock operation member, and unlocks the lid by disengaging the engaging part in a small diameter state where the spiral spring is rolled up by the lock operation member.SELECTED DRAWING: Figure 3
