    摘要： A spark plug for an internal combustion engine is provided which includes a metal shell, a porcelain insulator, a center electrode, a main ground electrode, and auxiliary ground electrodes. Each of the auxiliary ground electrodes has an end face facing the insulator to define an auxiliary spark gap. The end face includes an increasing-radial distance surface which is located at a distance from a longitudinal center line of the spark plug in a radial direction thereof which increases as approaching to the metal shell. The insulator nose has a wall thickness T meeting a relation of 0.3 mm≦T≦0.7 mm. This avoids a great local increase in electrical field strength on the auxiliary ground electrode to minimize excessive discharge within the auxiliary spark gap to enhance carbon fouling resistance and durability of the spark plug.

    摘要： A spark plug for an internal combustion engine is provided which includes a metal shell, a porcelain insulator, a center electrode, a main ground electrode, and auxiliary ground electrodes. Each of the auxiliary ground electrodes has an inner side surface facing the center electrode through the porcelain insulator to define an auxiliary spark gap between itself and a nose of the porcelain insulator so as to occupy a minimum distance between the porcelain insulator and the auxiliary ground electrode. This avoids a great local increase in electrical field strength on the auxiliary ground electrode to minimize excessive discharge within the auxiliary spark gap to enhance carbon fouling resistance and durability of the spark plug.

    摘要： Provided is an inverted pendulum mobile vehicle such as a single-passenger coaxial two-wheel vehicle which is capable of turning with a small turning radius without causing discomfort to a rider or a vehicle occupant or causing a cargo or the like on the vehicle from shifting or falling off from the vehicle. The vehicle comprises a wheel supporting frame (12), a body frame (12) supported by the wheel supporting frame so as to be rotatable around a vertical axial line and carry a rider and or a cargo and a body coupler (52, 78, 70) that couples the body frame relative to the wheel supporting frame in a prescribed dynamic positional relationship. Thereby, even when the wheel supporting frame undergoes a rapid yaw movement either while traveling in a fore-and-aft direction or remaining stationary, the body frame that carries a vehicle occupant or a cargo is allowed to follow the yaw movement of the wheel supporting frame at a slower angular speed and/or acceleration/deceleration so that the vehicle occupant is prevented from experiencing discomfort and the cargo is prevented from shifting on the body frame or falling off from the vehicle.

    摘要： [Task] Provided is an omni-directional drive device that does not complicate the arrangement for a power source for a drive source such as an electric motor, and achieves a high durability and an ease of maintenance.[Solution] A drive force in a first direction is produced by a movement of a first moveable member (10) itself, and a drive force in a second direction is produced by the rotation of first free rollers (14) retained by the first moveable member, the rotation of the first free rollers (14) being caused by engagement with second free rollers (15) that are retained by a second moveable member (11) and rotative actuation of the second moveable member (11). Electric motors serving as drive sources may be mounted on base members (4 and 5).
