Abstract: PURPOSE:To lighten a violent shock in the initial stage of braking by interposing a buffer member between a blade driving lever and a brake lever at the beginning so that the abutting of the former on the latter is smoothly shifted to the contact between metals each other in the midst of braking. CONSTITUTION:When the engagement of a blade driving lever 8 is released, a front blade driving lever 8 is turned clockwise around an axis P with the energizing force of a front blade driving spring 12 and causes the front blade group 3 of a shutter to execute an opening traveling to an aperture part 1a. When the group 3 travels and approaches to a traveling completion position, the vertically folded part 8a of the lever 8 abuts on the buffer member 15 on the brake lever 13 with considerable impulse and engages with it. When the front blade group 3 travels more and approaches the completion position, a pin 9 planted on the edge part of the turning arm of the front blade driving lever 8 abuts on the abutting part 13e provided on the brake lever 13 and engages with it. Thus, the shock at the time of engaging is lightened and moderated with the deformation of the buffer member 15.
