ABSTRACT:
A seal structure includes a stationary member, a rotatable member disposed within the stationary member to divide an interior of the stationary member into two chambers, a seal member mildly pressed to the stationary member and the rotatable member, and a recess for collecting grease, formed in the rotatable member. The seal structure can be used as a seal between a rotatable member and a stationary member of an air supply and gas exhaust switching mechanism of a regenerative combustion burner.
