Document Type and Number:
Japanese Patent JP2016161725
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a camera focal plane shutter that is high in durability.SOLUTION: A camera focal plane shutter 100 comprises: a first driving pin 112 for driving a first shutter blade 103; a shutter base plate 102 that has a first long hole part 110 where the first driving pin 112 moves; and a first buffer member 108 that is attached to a bottom end of the first long hole part 110. The first buffer member 108 has: a pillar buffer part that extends in a thickness direction of the shutter base plate 102; and a first projection part that projects from the buffer part to abut against one principal surface of the shutter base plate 102. The buffer part has an abutting surface part that forms a surface abutting against the bottom end of the first long hole part 110, and the first projection part includes a tangent plane part that contacts with the abutting surface part when viewing from the thickness direction of the shutter base plate 102.SELECTED DRAWING: Figure 1
