Description

本態様の規制部は、伝達歯車と接触し伝達歯車と接触することにより伝達歯車から力を受ける方向側とは異なる方向側に延びる第1構成部を有するとともに、第1構成部が伝達歯車と接触することにより伝達歯車から力を受ける方向側に延びる第2構成部を有する。
このため、規制部に加わる力を第1構成部が延びる方向側に分散することができるとともに、規制部に加わる力を第2構成部で効果的に受け止めることができる。したがって、規制部が損傷することを抑制することができる。
The restricting portion of the present aspect has a first component that extends in a direction different from the direction in which the force is transmitted from the transmission gear by coming into contact with the transmission gear and contacting the transmission gear. It has a 2nd component part extended to the direction side which receives a force from a transmission gear by contacting.
Therefore, the force applied to the restriction portion can be dispersed in the direction in which the first constituent portion extends, and the force applied to the restriction portion can be effectively received by the second constituent portion. Therefore, it is possible to prevent the restriction portion from being damaged.

ここで、歯車13は扇型歯車であり、扇型の最外周部分(円弧部分)に歯32が形成されている。また、歯32の下側(+X方向側)の一部の領域には、小径円弧部52に当接する当接歯が設けられている。具体的には、歯32のうちの一部の歯(歯車13の回転移動方向における両端部側の1又は複数ずつの歯)は、他の歯に比べて+X方向において短く構成されている。そして、+X方向に短く構成されている歯の下部(+X方向側)に外周方向の長さが短い当接歯が構成されている。歯車13はこのような構成となっていることで、歯31が歯32と噛合う位置にあるときは歯31と歯32とが接触し、歯31が歯32と噛合う位置にないときは小径円弧部52における歯31が形成されていない部分と該当接歯とが接触する。すなわち、歯車13は、歯31が歯32と噛合う位置にあるときは歯31により拘束されて位置決めされ、歯31が歯32と噛合う位置にないときは小径円弧部52における歯31が形成されていない部分により拘束されて位置決めされる。このような構成により、歯車13は、歯車12に対して常に接触することとなり、がたつくことなく効果的に位置決めされる。 Here, the gear 13 is a fan-shaped gear, and teeth 32 are formed on the outermost peripheral portion (arc portion) of the fan-shaped gear. Further, a contact tooth that abuts the small-diameter circular arc portion 52 is provided in a part of the lower side (+X direction side) of the tooth 32. Specifically, some of the teeth 32 (one or more teeth on both end sides in the rotational movement direction of the gear 13) are configured to be shorter in the +X direction than other teeth. A contact tooth having a short outer peripheral length is formed on the lower portion (+X direction side) of the tooth that is short in the +X direction. With the gear 13 having such a configuration, when the tooth 31 is in a position where the tooth 31 meshes with the tooth 32, the tooth 31 is in contact with the tooth 32, and when the tooth 31 is not in a position meshing with the tooth 32, A portion of the small-diameter circular arc portion 52 where the tooth 31 is not formed contacts the corresponding contact tooth. That is, the gear 13 is constrained and positioned by the tooth 31 when the tooth 31 is in the position where it meshes with the tooth 32, and the tooth 31 in the small-diameter arc portion 52 is formed when the tooth 31 is not in the position where it meshes with the tooth 32. Positioned by being constrained by the uncovered portion. With such a configuration, the gear 13 is always in contact with the gear 12, and is effectively positioned without rattling.

また、図6〜図9で表されるように、本実施例の歯車12は、該歯車12の回転軸37を基準とする同心円の一部に歯31が設けられた噛合い部46を有する。そして、噛合い部46を歯車13の歯32と噛合わせることでステッピングモータ48の駆動力を歯車13に伝達する構成になっている。本実施例のダンパ装置1は、このような構成の歯車12を有することで、歯車12の噛合い部46を歯車13の歯32と噛合わせない状態を容易に作ることができる。したがって、歯車13を所定位置で停止させておく(すなわち、開閉板6を開位置又は閉位置に保つ)ことを容易にしている。
なお、上記のように、平板部53の小径円弧部52は、歯31の形成領域を除き、上側(−X方向側)は平面部61、角部54及び大径円弧部51とともに外周部38を構成するが、下側(+X方向側)は全体的に円弧状(円柱状)となっている。また、該小径円弧部52は、円周方向の一部の領域にのみ歯31を有している。そして、上記のように、歯車13は扇型歯車であり、扇型の最外周部分(円弧部分)に歯32が形成されている。また、歯32の下側(+X方向側)の一部の領域には、小径円弧部52に当接する当接歯が設けられている。歯車13はこのような構成となっていることで、歯31が歯32と噛合う位置にあるときは歯31により拘束されて位置決めされ、歯31が歯32と噛合う位置にないときは小径円弧部52における歯31が形成されていない部分により拘束されて位置決めされる。このような構成により、歯車13は、歯車12に対して常に接触することとなり、がたつくことなく効果的に位置決めされる。
Further, as shown in FIGS. 6 to 9, the gear 12 of the present embodiment has a meshing portion 46 in which teeth 31 are provided in a part of a concentric circle with the rotation shaft 37 of the gear 12 as a reference. .. Then, the meshing portion 46 meshes with the teeth 32 of the gear 13 to transmit the driving force of the stepping motor 48 to the gear 13. Since the damper device 1 of the present embodiment has the gear 12 having such a configuration, it is possible to easily make a state in which the meshing portion 46 of the gear 12 does not mesh with the teeth 32 of the gear 13. Therefore, it is easy to stop the gear 13 at a predetermined position (that is, keep the opening/closing plate 6 in the open position or the closed position).
In addition, as described above, the small-diameter circular arc portion 52 of the flat plate portion 53 has the upper surface (on the −X direction side) except the formation area of the teeth 31, the flat surface portion 61, the corner portion 54, and the large-diameter circular arc portion 51 together with the outer peripheral portion 38. However, the lower side (+X direction side) has an arc shape (cylindrical shape) as a whole. The small-diameter circular arc portion 52 has the teeth 31 only in a partial area in the circumferential direction. Then, as described above, the gear 13 is a fan-shaped gear, and the teeth 32 are formed on the outermost peripheral portion (arc portion) of the fan-shaped gear. Further, a contact tooth that abuts the small-diameter circular arc portion 52 is provided in a part of the lower side (+X direction side) of the tooth 32. With such a configuration, the gear 13 is constrained and positioned by the tooth 31 when the tooth 31 is in a position where it meshes with the tooth 32, and has a small diameter when the tooth 31 is not in a position where it meshes with the tooth 32. The arcuate portion 52 is constrained and positioned by the portion where the teeth 31 are not formed. With such a configuration, the gear 13 is always in contact with the gear 12, and is effectively positioned without rattling.
