Abstract

A damper device, wherein a toothless gear (38) of a wheel set (32) constituting the damper device (1) has an arc-shaped outer peripheral portion (52) in the circumferential direction of a tooth portion (51), and the arc-shaped outer peripheral portion ( 52) Has an outer peripheral surface (52a) having the same diameter as the addendum circle (51a). The part of the sector gear (39) driven by the missing tooth gear (38) facing the outer peripheral surface (52a) is cut off, and the sector gear (39) has The other side X2 enters the first tooth (68) in the addendum circle (51a) and is adjacent to the first tooth (68) and can be connected to the outer peripheral surface ( 52a) The abutting second tooth (69). The second tooth (69) is cut from one end of the other side X2 in the X direction toward one side X1 from the top side of the tooth, and the tooth end surface (69a) of the second tooth (69) and the arc-shaped outer peripheral portion (52 ) on the same plane.

Description

technical field [0001] The present invention relates to a damper device that opens and closes an opening with a baffle. Background technique [0002] Patent Document 1 describes a damper device that opens and closes an opening constituting a part of a cold air passage of a refrigerator with a damper. The damper device of this document rotates the baffle through a drive mechanism having a stepping motor and a wheel set. The shutter moves between a closed position that closes the opening and an open position that opens the opening. The wheel set includes a toothless gear and a sector gear driven by the toothless gear. [0003] The tooth-missing gear has an outer peripheral portion having an outer peripheral surface along an addendum circle of the tooth portion at a position adjacent to the tooth portion in the circumferential direction. The length in the axial direction of the outer peripheral portion is shorter than the tooth width of the tooth portion, and the outer perip...
