2results about How to "Suppress exposure" patented technology

The objective of this invention is to suppress the exposure of the busbar during a frontal collision of a vehicle. An engine starter unit (electrical equipment) is mounted in the engine compartment. A B-terminal is located at the front of the engine starter unit. The busbar is connected to the B-terminal and extends rearward. A base and a cover hold and cover the busbar. The base and cover are insulated. The base and busbar are fixed together to the engine starter unit. The cover and base engage via latches. A front wall portion is formed on the base at a position forward of the cover. The front wall portion covers the front surface of the cover when viewed from the front of the vehicle.

The present invention provides a shield tunneling machine, which is provided with: a plurality of obstacle cutting cutter heads, which include a base material and a plurality of hard blades fixed to the base material in a state of protruding further in the excavation direction than the base material and harder than the base material, and cut underground obstacles; a cutter disc, which is provided with the obstacle cutting cutter heads and rotates along with excavation; and a shield tunneling machine body, which is provided with a cutter disc at the front end in the excavation direction. The plurality of obstacle cutting cutter heads are respectively configured such that the plurality of hard blades are arranged at intervals in the rotation direction of the cutter disc, and in the rotation direction of the cutter disc, the hard blades located on the outermost side in the rotation direction of the cutter disc are arranged closer to the inside than the base materials located at both ends in the rotation direction of the cutter disc.
