摘要:
In the focal plane shutter for cameras, a shutter base plate, an shank for attaching the first blade drive component and the second blade drive component respectively so as to enable to be rotated, an shank for attaching a set component so as to enable to be rotated, and an shank for attaching the first blade and the second blade so as to enable to be rotated respectively are made of synthetic resins. Each of the shanks is fabricated after a shutter base plate was fabricated beforehand, and grooves for sump having cross section of V letter shape are formed at the same interval of angle extending toward the axial direction of the shank at the circumferential side surfaces of the shanks.
