摘要： A gas exhaust structure of a battery includes a rupture valve formed in a battery body, and a pipe unit composed by integrating a coupling pipe and an exhaust pipe with each other. A one-side opening of the coupling pipe is coupled to the rupture valve. The exhaust pipe is coupled to an other-side opening of the coupling pipe, guides gas that spouts out from an inside of the battery body through the rupture valve and the one-side opening of the coupling pipe, and exhausts the gas to an outside. The exhaust pipe is arranged to be offset with respect to the rupture valve without allowing an extended line that passes through a center of the rupture valve and a centerline of the exhaust pipe to be perpendicular to each other.

摘要： A focus control circuit controls focus of a laser light by using an objective lens actuator. A tracking control circuit controls tracking of the laser light by using the objective lens actuator. The lens actuator includes a fixed unit including two magnets; and a moving unit arranged between the two magnets and including the objective lens, a lens holder, a focus coil, and a tracking coil. The tracking coil is provided on the lens holder such that the position of a tracking coil center in a focus direction is located more toward the objective lens side than the position of a magnetic circuit center of each magnet in the focus direction.
