  • Publication number: 20240116719
    Abstract: A transfer robot includes a first arm provided rotatably around a first axis which extends along a vertical direction, a second arm connected to the first arm rotatably around a second axis which extends along the vertical direction, an arm distal end portion which is configured to be connected to a workpiece holder to hold a workpiece and which is connected to the second arm rotatably around a third axis which extends along the vertical direction, and a posture adjuster configured to rotate the workpiece around a first posture adjustment axis which intersects both the third axis and a direction extending toward the arm distal end portion away from the third axis.

  • Patent number: 11679811
    Abstract: A front vehicle-body structure for reducing second-order vibration of a windshield, and improving NVH performance in a vehicle cabin. A tower bar coupling each of left and right front suspension housings with a region around a vehicle-width-direction center portion of a cowl forming a lower edge of an opening for a front windshield has a center portion extending in a vehicle width direction along the cowl. A bracket extending from the cowl toward a front of a vehicle is provided in a region including a vehicle-width-direction center portion of the front windshield in the lower edge of the opening. The center portion of the tower bar is fixed to the bracket from above, and a reinforcement member supporting the fixing region from below is provided.

  • Patent number: 11584446
    Abstract: A front vehicle-body structure which reduces third-order vibration of a windshield, and improves NVH performance in a vehicle cabin. A front windshield fixed to an edge portion of an opening formed in a vehicle body, a pair of left and right front suspension housings, a cowl forming a lower edge of the opening for the front windshield, and a tower bar coupling each of the left and right front suspension housings with a region around a vehicle-width-direction center portion of the cowl are provided. Node members, each of which locally improves bending rigidity of the cowl, are disposed in two positions in the cowl that divide a bonding surface to a windshield lower edge into generally three equal parts in the vehicle width direction, and the tower bar is fixed between respective positions of the two node members in the cowl.
