As a conventional vertical vacuum cleaner, as shown here, the main body 1 generating the suction force is coupled to the upper portion of the suction body 2 by using the rotating shaft (1a), to maintain the standing state of the main body (1) The main assembly apparatus 3 for this purpose is comprised in the one end side of the rotating shaft 1a.

The main body raising device 3 is composed of a cam 3a press-fitted to one end of the rotating shaft 1a and a locking portion 3b, and a pedal 3c for the user to step on the foot to control the rotation of the cam 3a. . The pedal 3c has a central portion coupled to the shaft 3d so as to be rotatable on the side surface of the suction body 2, and includes a latch portion extending upwardly bent to contact the engaging portion 3b of the cam 3d. 3e). And the torsion spring 3f which elastically supports so that the latch part 3e may contact the outer peripheral surface of the cam 3a is always engaged. The torsion spring 3f has a body portion fitted to the shaft 3d, one end of which is coupled to the latch portion 3e, and the other end of which is coupled to the suction body 2, respectively. Therefore, since the latch portion 3e of the pedal 3c is always elastically supported to the front side by the torsion spring 3f, the tip of the latch portion 3e is always in contact with the outer circumferential surface of the cam 3a.

Next, the operation of the vertical vacuum cleaner configured as described above will be described. First, in the vertical vacuum cleaner, when the main body 1 is perpendicular to the suction body 2, as shown in FIG. 1, the latching portion 3e of the pedal 3c is caught by the latching portion 3b of the cam 3a. ), The rotating shaft 1a cannot be rotated and is interrupted. In this state, when the user presses on the pedal 3c to overcome the elastic force of the torsion spring 3f, the latch portion 3e is spaced apart from the locking portion 3b of the cam 3a so that the rotation shaft 1a can freely rotate. And the main body 1 is rotatable on top of the suction body 2. When the pedal 3c is released, the latch portion 3e is already separated from the locking portion 3b, so that it does not interfere with the rotational movement of the rotation shaft 1a in contact with the outer circumferential surface of the cam 3a.

Therefore, the user grasps the handle part (not shown) provided at the upper end of the main body 1 slightly lying down, and performs cleaning while moving the suction body 2. Then, after the cleaning is completed, when the main body 1 is placed upright again, the latch portion 3e, which is elastically supported by the torsion spring 3f, is caught by the catching portion 3b of the cam 3a again, and the rotating shaft 1a By interruption, as shown in FIG. 1, the main body 1 is fixed in the upright position of the inhalation body 2. As shown in FIG.

However, the conventional body raising device 3 has a torsion spring 3f configured to elastically support the latch portion 3e, which is fitted on the shaft 3d to which the pedal 3c is coupled, and one end thereof is latched. Since the other end portion (3e) is fixed to the suction body (2), the assembly thereof is difficult, and there is a problem that the manufacturing cost increases due to the addition of parts.

The present invention is to solve such a problem, an object of the present invention is to be bent extending to the suction body is provided with an elastic deformation integrally configured to support the latch portion of the pedal while the body, to facilitate the assembly of the main assembly device in the production line It is to provide a vertical vacuum cleaner to reduce the manufacturing cost.
