To suppress resonance of a cover member without increasing the number of components.SOLUTION: A cover member 1 has a top plate unit 1 with irregularities formed thereon. The top plate unit 1 has, in a top view, a semicircular shape in which an oval shape is divided along a minor axis, a first edge in a first side direction is formed into an arc shape, and a second edge in the first side direction is linearly formed. The irregularities are formed by a first flat surface 10 and second flat surfaces 11a, 11b different in height. The first flat surface 10 is formed away from the second edge. The second flat surfaces 11a, 11b are formed connected to the second edge. A rib unit 12 extending from the first flat surface 10 in a first side direction to the second edge is formed on the top plate unit 1. The rib unit 12 divides the second flat surfaces 11a, 11b in a second side direction perpendicular to the first side direction at the second edge.SELECTED DRAWING: Figure 1

    【課題】部品点数を増やすことなくカバー部材の共振を抑制する。【解決手段】カバー部材1は、凹凸が形成された天板部1を有する。天板部1は、上面視で、長円形状を短軸に沿って分割した半長円形状を有しており、第1辺方向の第1端が円弧状に形成され、第1辺方向の第2端が直線状に形成されている。上記凹凸が、高さが異なる第1平坦面10と第2平坦面11a、11bによって形成され、第1平坦面10は第2端から離間して形成され、第2平坦面11a、11bは第2端に繋げて形成される。第1平坦面10から第1辺方向に伸びて第2端に至るリブ部12が天板部1に形成され、リブ部12は、第2端において、第1辺方向に直角な第2辺方向に第2平坦面11a、11bを分割する。【選択図】図1
