  • Patent number: 11325561
    Abstract: In a present webbing retractor, when a stopper is pushed and moved by a conical portion of a moving member, the stopper abuts a moving member main body of the moving member between a rotating member and an axial direction distal end of a cylinder, and moreover, is moved toward a side of a portion of engagement of the moving member main body with first teeth and second teeth of the rotating member, while deforming the moving member main body. Due thereto, expansion, toward a side in a direction orthogonal to an axis, of the moving member main body can be suppressed.

  • Patent number: 11007975
    Abstract: In a webbing retractor, due to a moving member being moved toward an axial direction distal end side, and first teeth and second teeth of a rotating member piercing the moving member, the rotating member is rotated in a take-up direction. Here, at the moving member, a sectional surface area, in a direction orthogonal to an axis, of a small diameter portion that is at an axial direction distal end side is made to be small as compared with a moving member main body that is at an axial direction proximal end side. Therefore, resistance to movement of the moving member can be reduced.

  • Publication number: 20210125726
    Abstract: According to one embodiment, a healthcare support system includes a memory and a hardware processor connected to the memory. The hardware processor predicts a risk value of a disease based on medical checkup data for a medical examinee. The hardware processor sets a reduction target for the risk value of the disease, and sets a plurality of second factors constituting search targets among a plurality of first factors relating to the disease and a search range for each of the second factors. The hardware processor searches, by using a predetermined search method, in the search range for each of the second factors, for a target value candidate of each of the second factors so that the risk value of the disease is brought close to the reduction target.
