RACK DRIVING DEVICE AND SANITARY WASHING TOILET SEAT DEVICE
To provide a rack driving device that prevents interference contact of a drive gear and a driven gear and enables smooth motion transmission when a rack engages with the driven gear stopped at a predetermined phase in the rack driving device in which the drive gear and the driven gear are disposed apart from each other between a pair of racks.SOLUTION: The drive gear and the driven gear are configured such that a distance between a rack reference line and a center of the driven gear is equal to or greater than the distance between the reference line and the center of the drive gear, and such that the distance between the center of instantaneous rotation and the center of the driven gear in a relative movement of the rack and the driven gear is less than the distance between the center of the instantaneous rotation and the center of the drive gear in the relative movement of a drive gear movement and a rack movement. Also, the driven gear has a stop phase defined to be stopped at a predetermined phase when the rack separates from the driven gear, and the stop phase is determined to start contact at a position on an action line between the rack and the driven gear when the rack engages with the driven gear.SELECTED DRAWING: Figure 15
【課題】一対のラック間に互いに離間して駆動歯車および従動歯車とが配置されたものにおいて、所定位相で停止した従動歯車に対してラックが係合するときに、両者の干渉的な接触を防止し、円滑な運動伝達を可能とする。【解決手段】駆動歯車および従動歯車は、ラックの基準線と従動歯車の中心との距離が、同基準線と駆動歯車の中心との距離以上で、且つ、ラックの運動と従動歯車の運動との相対運動における瞬間回転中心と従動歯車の中心との距離が、駆動歯車の運動とラックの運動との相対運動における瞬間回転中心と駆動歯車の中心との距離未満となるように構成される。また、従動歯車は、ラックが従動歯車から分離する際に、所定の位相で停止されるように停止位相が定められ、停止位相は、ラックが従動歯車と係合する際に、ラックと従動歯車との作用線上の位置で接触開始するように定められている。【選択図】図１５
