Abstract: In a handle device for a vehicle door, a base member made of a synthetic resin is provided with: a pin support part having a support hole; and a pair of restricting walls which flexes so as to allow a pin to pass through when the pin is inserted into the support hole and which opposes an end part of the pin after insertion of the pin is completed. The pin is formed so as to integrally have: a pin main portion being formed in a round bar shape having a constant diameter and a circular cross-sectional shape and being inserted from one end side through the support hole; and a large diameter portion being coaxially connected to the other end of the pin main portion.
