LOAD DETECTION DEVICE FOR VEHICLE SEAT
First Claim
1. A load detection device for a vehicle seat mounted between a floor side mounting mechanism and a seat side mounting mechanism and measuring a load applied by an occupant seated on the vehicle seat, comprising:
- a shaft member adapted to be fixed to one of the floor side mounting mechanism and the seat side mounting mechanism;
a strain generating member fixed to the shaft member and including a hole into which the shaft member is press-fitted for fixing the strain generating member to the shaft member;
a strain gauge attached to the strain generating member;
the shaft member of which surface hardness is specified to be lower than a surface hardness of the hole of the strain generating member and including a scraping projecting portion scraped off by means of the hole in a case where the shaft member is press-fitted to the hole; and
an interspace formed between the strain generating member and the shaft member and positioned next to the scraping projecting portion.
