That is, the teeth of :::: will become larger, for example, the claws and the gears become smaller. Since the "strength relationship" of the household cannot make the position of the claws and the gears larger, and the gear number of the gears becomes thicker than the pitch, the number of the angle switching is also small, and the fine adjustment cannot be performed. In this way, the problem to be solved is that the number of segments to be switched can not be changed. In addition, the metal parts are changed as a whole because of the large size of the components.

Description of the invention (small) Force, so the first arm and the second arm will never swing in the unfolding direction. Furthermore, the swing is suppressed not only by the engagement of the gear portion, but also by the abutting force of the floating wedge and the wedge surface, the engagement with the gear portion, and the pressing force, thereby suppressing the swing. The gears of the gears are smaller and can withstand larger loads. Further, by reducing the gear of the gear portion, the number of gears of the gear portion can be increased, and the number of segments of the angle switching can be increased. Therefore, fine adjustment of the folding angle can be performed. Since the second arm is formed by bending a single plate body, the plate body has two gear plate portions symmetrically left and right, thereby reducing the number of parts and reducing the molding time. Further, since the gear portion is composed of two-piece gear plate portions which are parallel to each other, the floating wedge member does not sway to the left and right and stably engages the gear portion without causing a malfunction. Because the different g-intrusion preventing member pivotally connected in the box portion and arbitrarily swinging around the first axis center can effectively prevent foreign matter such as garbage from intruding between the gear portion and the floating wedge member, causing the stop operation, And can prevent the occurrence of obstacles. Since the floating wedge is formed by cutting a long-length pull-out material formed of an iron steel material, it is easier to manufacture and is advantageous for mass production. Since the detachment preventing cover can surround the box portion from the left and right outer sides, the floating wedge member can be surely prevented from falling off from the wedge-shaped window portion, and the malfunction or malfunction of the floating wedge member can be prevented. The cover prevents the cover from comprising two left and right side walls, a bottom wall and a rounded wall portion, the bottom wall surrounding the box portion from below and connecting the two left and right side walls
