Description
このような構成の振動板15は、図示せぬ駆動回路から電極33を介して圧電素子30,31に交流電圧が印加されると、圧電素子30,31が伸縮することによって振動するようになっている。その際、図4に示すように、振動板15が長手方向に伸縮する縦振動で振動するようになっており、これにより振動板15は図2中矢印で示す振動板15の長手方向に振動することになる(無負荷状態、つまり突起部36が車軸10に接触していない状態)。このような振動板15の振動によって突起部36が変位する。この際、突起部36と車軸11の外周面との間に生じる摩擦により車輪11が突起部36の変位に伴って移動することになる。これにより、車輪11が図2中反時計方向に駆動され、この車輪装置が走行するようになっている。 When an AC voltage is applied to the piezoelectric elements 30 and 31 from a drive circuit (not shown) via the electrodes 33, the diaphragm 15 having such a configuration vibrates due to expansion and contraction of the piezoelectric elements 30 and 31. ing. At that time, as shown in FIG. 4, the diaphragm 15 vibrates by vertical vibration that expands and contracts in the longitudinal direction, whereby the diaphragm 15 vibrates in the longitudinal direction of the diaphragm 15 indicated by the arrow in FIG. (A state in which no load is applied, that is, a state in which the protrusion 36 is not in contact with the axle 10). The protrusion 36 is displaced by the vibration of the diaphragm 15. At this time, the wheel 11 moves with the displacement of the protrusion 36 due to the friction generated between the protrusion 36 and the outer peripheral surface of the axle 11. As a result, the wheel 11 is driven counterclockwise in FIG. 2, and the wheel device travels.
図16に示すように、この送風装置は、羽根ユニット155と、振動板15とを備えている。羽根ユニット155は、回転軸152を有しており、この回転軸152から放射状に複数(図示は4つ)の羽根151が設けられている。羽根151の先端側は、円環状の羽根保持部材(リング部材)158に取り付けられており、これにより羽根保持部材158の回転に伴って羽根151および回転軸152が回転するようになっている。このように羽根151を回転させることにより、主に図の紙面垂直方向に送風するようになっている。 As shown in FIG. 16, this blower includes a blade unit 155 and a diaphragm 15. The blade unit 155 has a rotating shaft 152, and a plurality of blades 151 (four in the figure) are provided radially from the rotating shaft 152. The tip end side of the blade 151 is attached to an annular blade holding member (ring member) 158 , whereby the blade 151 and the rotation shaft 152 rotate as the blade holding member 158 rotates. By rotating the blade 151 in this way, air is mainly blown in the direction perpendicular to the paper surface in the figure.
