In order to solve the above-mentioned problems, the present invention provides a vehicle door lock device in which the end of a shaft for pivotally supporting a rotating member is fixed to a plate-shaped case in a substantially perpendicular manner, and the present invention provides a door lock device for a vehicle in which an end of a pivot shaft for pivotally supporting a rotating member is fixed to a plate-shaped case in a substantially orthogonal manner. A raised part having an outer peripheral part raised with an inclination angle of 90° or less and a shaft hole through which the pivot shaft passes through the center is provided, and the raised part is provided at the end of the shaft passed through the shaft hole. A head portion is provided which has a sloped surface substantially perpendicular to the outer circumferential portion and is in close contact with the raised portion.

２１ｄ，２２ｄを形成している。 As shown in FIG. 3, at the upper end of each pivot shaft 21, 22, there are tapered portions 21a, 22a complementary to the reverse countersunk hole 24b, and small-diameter shaft portions 21b, 2
2b are integrally formed, and the tapered parts 21a, 22
The small diameter shaft portion 21 until a is brought into close contact with the countersunk hole 24b.
After fitting b, 22b into the shaft hole 24, the small diameter shaft portion 21
By caulking the tips of b, 22b, the small diameter shaft parts 21b, 22b are deformed, and each pivot shaft 21, 2
As shown in phantom lines in FIG. 3, a countersunk hole 24 is provided at the upper end of 2 in a tapered shape that widens upward so as to be substantially perpendicular to the outer circumferential portion 23a of the raised portion 23.
Head portions 21d and 22d are formed having inclined surfaces 21c and 22c that are in close contact with a.
