Abstract: A vehicle body lower structure according to one aspect includes: a pair of side rails disposed apart from each other in a width direction of a vehicle and extending in a front-rear direction of the vehicle; a pair of hydrogen tanks respectively disposed outside the pair of side rails in the width direction; a pair of protection members configured to respectively protect the pair of hydrogen tanks from external impact; and a battery supported by the pair of side rails between the pair of protection members.

Abstract: A vehicle body lower structure according to one aspect includes a frame including a side rail extending in a front-rear direction of a vehicle, a motor configured to generate regenerative power, and a brake register configured to convert the regenerative power into thermal energy, in which the brake register is disposed immediately below the side rail so as to receive traveling wind while the vehicle is traveling.

Abstract: A motorcycle includes a body frame, an engine, a lead-in duct, and an air cleaner case. An air cleaner includes a convex cleaner element protruding in a direction opposite to a direction extending toward the lead-in duct, and a convex support frame that supports the inner surface of the cleaner element. The support frame includes an outer frame that supports a periphery of the cleaner element. The cleaner element includes a convex element body and a seal provided adjacent the peripheral edge of the element body to project toward the inner surface of the element body so as to work together with the periphery of the element body to hold the outer frame. The periphery of the element body has a smaller thickness than the other portions of the element body.
