Abstract: A seal structure is provided to block a clearance between a rotational casing and a fixed housing for driving a crawler of a crawler vehicle. A seal ring is held in a first annular holding groove provided in the fixed housing together with a first O-ring that biases the seal ring toward the outside of the first holding groove. A second holding groove having an opening facing the first holding groove is provided in the rotational casing to hold a slide ring having a higher rigidity than that of the seal ring together with a second O-ring that biases the slide ring toward the seal ring. A foreign object such as mud is thereby prevented from invading a gear chamber without increasing a frictional loss.

Abstract: A production apparatus for a liquid containing gas bubbles includes a casing, a pump unit, and a gas bubble-mixing unit. The casing is provided with a main flow channel for a liquid, the main flow channel having a liquid inflow port and a liquid outflow port. The pump unit is disposed in the main flow channel and pumps the liquid to the liquid outflow port from the liquid inflow port. The gas bubble-mixing unit includes a first choke portion that is disposed in the main flow channel and has an inner diameter decreased and a gas supply channel that supplies the first choke portion with a gas.
