  • Patent number: 12241799
    Abstract: A load sensor device includes a load sensor that has a pressure receiver, a housing that accommodates the load sensor, an elastic member that receives a load and presses against the load sensor, and a pressing member that is provided between the elastic member and the load sensor. The pressing member has a rigid presser capable of coming into contact with the pressure receiver, and an elastic supporter that supports the rigid presser on the housing. A gap is provided between the rigid presser and the pressure receiver in a state where the load is not applied to the elastic member. The elastic supporter elastically deforms to reduce the gap between the rigid presser and the pressure receiver when the load is applied to the elastic member. The load sensor device further includes a shock absorber capable of alleviating elastic deformation of the elastic supporter.

  • Publication number: 20230152168
    Abstract: A load sensing apparatus according to an aspect of the present invention includes a load sensing element including a pressure sensing portion, a housing that houses the load sensing element, and a pressing member supported by the housing, wherein the pressing member includes an elastic member that receives a load, a stiff pressing portion that is to come into contact with the pressure sensing portion, and an elastic supporting portion that supports the stiff pressing portion in the housing. When no load is applied to the pressing member, a gap is formed between the stiff pressing portion and the pressure sensing portion.
