A sheet folding device, an image forming device, and a gear connecting mechanism

Japanese Patent JP6269584

B2

A sheet folding device (73) includes first and second rollers (734, 735), a blade (733), first and second parallel pins (811, 821), and first and second gears (734g, 735g). The first and second parallel pins (811, 821) are passed through first and second pin through-holes (812, 822) penetrating through first and second shaft portions (7340, 7350) in a direction perpendicular to a longitudinal direction of the shaft portions (7340, 7350). The first and second gears (734g, 735g) have first and second shaft through-holes (814, 824) through which the first and second shaft portions (7340, 7350) are passed, and first and second grooves (815, 825) in which the first and second parallel pins (811, 821) are inserted, respectively. Projection portions (826) formed on inner side wall of the second groove (825) and projecting from both sides of the second shaft portion (7350) cause the second parallel pin (821) to closely contact a side wall that is, in the second groove (825), opposite to the projection portions (826), and cause the second parallel pin (821) to closely contact a portion of the second pin through-hole (822).
