1. A storage box seal structure in which a storage box includes: a housing including an opening; and a lid member that rotates around a turning axis provided at a front portion of the housing and that is openable and closeable by an operation portion provided at a rear portion of the housing, the storage box seal structure comprising:
a recess provided to the lid member;
a seal member provided in the recess; and
a projection that is provided at a periphery of the opening of the housing and that comes into contact with the seal member for sealing, wherein
the storage box seal structure has, at the opening, a centering structure for guiding opening and closing of the lid member,
the centering structure includes a guide portion that comes into contact with a first rib and a second rib projecting from opposite edges of the recess of the lid member and that guides at least one of the first rib and the second rib at opening and closing, and
the guide portion is provided, in the periphery of the housing, closer to the turning axis than a total-length center of the storage box in a direction perpendicular to the turning axis is.
2. The storage box seal structure according to claim 1 , wherein the guide portion guides both the first rib and the second rib.
3. The storage box seal structure according to claim 1 , wherein
the seal member is hollow, and
a seal rib formed on the projection presses the seal member to seal a gap between the recess and the projection.
4. The storage box seal structure according to claim 1 , wherein the centering structure is provided in a direction intersecting the turning axis of the lid member in the storage box.
5. The storage box seal structure according to claim 1 , wherein the centering structure is provided at positions that do not overlap each other in a direction of the turning axis of the lid member in the storage box.
6. The storage box seal structure according claim 4 , wherein the first rib and the second rib have inclined portions on the side closer to the turning axis.
7. The storage box seal structure according to claim 1 , wherein the guide portion has an inclined surface on a face facing the first rib or the second rib.
8. The storage box seal structure according to claim 1 , wherein a pair of the centering structures are provided at left and right edges in the periphery of the opening of the housing, the left and right edges intersecting the turning axis.
