LOAD DETECTION DEVICE FOR VEHICLE SEAT

PROBLEM TO BE SOLVED: To provide a load detection device for a vehicle seat, capable of preventing internal stress due to press-fitting of a shaft member from being generated in a strain-generating member. SOLUTION: The shaft members 30, 40 are press-fitted to holes 21-23 of the strain generating me...

Summary:PROBLEM TO BE SOLVED: To provide a load detection device for a vehicle seat, capable of preventing internal stress due to press-fitting of a shaft member from being generated in a strain-generating member. SOLUTION: The shaft members 30, 40 are press-fitted to holes 21-23 of the strain generating member 20 to which strain gauges G1 and G2 are attached. The shaft members 30, 40 includes shaft bodies 32, 42 press-fitted to the holes 21-23 from openings at one side of the holes 21-23 and head parts 31, 41 provided integrally at one end side of the shaft bodies 32, 42 and engaged with the holes 21-23. The shaft bodies 32, 42 include: scraping projecting parts 32b, 42b formed so as to include surface hardness lower than that of the holes 21-23 of the strain generating member 20 and scraped off by the holes 21-23; and non-press-fitting parts 32a, 42a adjacent to the scraping projecting part 32b, 42b in the circumferential direction and not imparting mutual pressure in gaps to the holes 21-23. Clearance spaces accommodating the scraped parts of the scraping projecting part 32b, 42b are formed between the strain generating member 20 and the shaft members 32, 42 at the openings at one side of the holes 21-23.
