WHEEL, LOCK DEVICE HAVING THE WHEEL, AND DOOR BODY FALL PREVENTION DEVICE HAVING THE LOCK DEVICE
To provide a wheel that is formed by connecting a boss capable of accepting a shaft and a tabular element that has a locked portion on its outer periphery and an opening for accepting the boss, and has enough strength to withstand the impact when a lock member is locked to the locked portion.SOLUTION: A wheel 9 is formed of a boss 90 capable of accepting a shaft and a tabular element 91 that has one or a plurality of locked portions on its outer periphery and an opening for accepting the boss 90. An outer peripheral surface 900 of the boss 90 and an inner peripheral surface 913 of the opening of the tabular element 91 have shapes so that the boss 90 can be inserted in the opening and the force in a circumferential direction can be transmitted to each other in an insertion state. A first corner formed of the outer peripheral surface 900 of the boss 90 and a first surface 91A of the tabular element 91 and a second corner formed of the outer peripheral surface 900 of the boss 90 and a second surface 91B of the tabular element 91 are at least partially welded.SELECTED DRAWING: Figure 13
【課題】シャフトを受け入れ可能なボスと、外周に被係止部を備え、前記ボスを受け入れる開口が形成された板状要素と、を接続してなるホイールにおいて、前記被係止部にロック部材が係止した時の衝撃に耐え得る強度を備えたホイールを提供する。【解決手段】シャフトを受け入れ可能なボス９０と、外周に１つあるいは複数の被係止部を備え、ボス９０を受け入れる開口が形成された板状要素９１と、からなるホイール９であって、ボス９０の外周面９００と板状要素９１の開口の内周面９１３は、開口にボス９０を挿通可能であり、挿通状態において、互いに周方向の力が伝達可能な形状を有しており、挿通状態において、ボス９０の外周面９００と板状要素９１の第１面９１Ａで形成される第１隅部、ボス９０の外周面９００と板状要素９１の第２面９１Ｂで形成される第２隅部の少なくとも一部が溶接されている。【選択図】図１３
