Abstract: A culture system and a culture device each can minimize the burden on workers and can effectively prevent the effect of temperature changes on culture by performing manipulation of a multilayer culture vessel and the culture in sequence in the same space. The culture system comprises a housing with an internal space in which a multilayer culture vessel including a plurality of trays therein is placed, and a manipulator manipulating the multilayer culture vessel while the multilayer culture vessel is kept in a state placed within the internal space. The multilayer culture vessel is communicated with a liquid supply tube such that a fluid material can be introduced into the multilayer culture vessel from an outside of the housing via the liquid supply tube, or that a fluid can be discharged from the multilayer culture vessel to the outside of the housing via the liquid supply tube.

Abstract: A steering structure for a saddle riding vehicle includes a suspension arm, a head pipe supported by a tip portion of a suspension arm, a stem shaft pivotably inserted through the head pipe, a front fork structure body integrally pivotably connected to a lower end portion of the stem shaft, a handle support section disposed above the head pipe, a handle steerably supported by the handle support section, and a bending link configured to transmit a steering operation of the handle toward a front wheel, wherein the bending link has an upper end portion connected to a side of the handle and a lower end portion connected to a side of the front fork structure body.

Abstract: A seat device for a vehicle includes a seat for supporting a lower body of a vehicle occupant, and a backrest for supporting an upper body of the occupant. The seat device further includes an arresting portion that is stored in a storage position disposed in the seat. The arresting portion is configured to be deployed from the storage position and restrain a part of the lower body of the occupant from moving forward in the event of a collision of the vehicle.

Abstract: An authority transfer device is used for a vehicle having an autonomous driving mode in which driving operation is autonomously performed for a driver and a manual driving mode in which driving operation is manually performed by the driver using at least a steering wheel. The authority transfer device includes a controller configured, when switching from the autonomous driving mode to the manual driving mode, to transfer a driving authority of the vehicle to the driver on condition that at least a grip of the driver on the steering wheel is detected. The controller notifies the driver that the driving authority will be transferred before the driving authority is transferred.
