A handle portion 9 is formed in the center of the upper surface of the blower case 3. A push button 10 for winding and unwinding the cord reel is attached to one of the rear upper corners of the blower case 3, and a push button switch device 11 for stopping the electric blower is attached to the other side. ing.

A mounting recess 12 is formed in a corner of the blower case 3 so as to extend from the upper surface to the adjacent side and rear surfaces. The push button switch device 11 is mounted in the mounting recess 12. The push button switch device 11 includes a switch body 1 having a seesaw type operating body 13 fixed to the bottom surface of the mounting recess 12.
4, a push button 15 that is mounted so as to cover the mounting recess 12 and forms a surface that is continuous with the top, side, and rear surfaces of the blower case 3; It consists of a pendulum body 16. The seesaw operating body 13 has a substantially semicircular arc shape, and the center of its lower surface is pivotally supported by a support portion 18 at the center of the upper surface of the frame portion of the switch body 14 via a pivot 17. When the operating body 13 is operated with a seesaw, the switch body 14 is turned on and the electric blower is stopped. By forming a substantially W-shaped recess in the center of the upper surface of the operating body 13, a substantially chevron-shaped portion 19 is formed.
A first pressing portion 20 and a second pressing portion 21 are formed with the boundary between them. The top of the substantially chevron-shaped portion 19 is located at the support portion 18 when the operating body 13 is positioned horizontally.
It is located above the axis 17 of. Due to the structure of the switch body 14, the operating body 13 is not held in a neutral state, but is held in a lowered state when pressed. The push button 15 is pivotally supported at the upper part of the inner surface of one side of the mounting recess 12 . The pushbutton 15 is supported in a cantilever manner by a pivot shaft 22, and a guide shaft 2
3 ensures stable rotation of the push button 15 and prevents it from coming off from the mounting recess 12. The inner surface of the push button 15 includes a stopper 24 that comes into contact with the bottom surface of the mounting recess 12 to prevent the push button 15 from being pressed when the push button 15 is pressed and rotated, and a stopper 24 that automatically returns the push button 15 to the state before being pressed. A locking part 26 for holding the spring body 25, a mounting part 27 for the pendulum body 16, and a support part 29 for the spring body 28 for biasing the pendulum body 16 in the downward direction are formed.
The pendulum body 16 is connected to the push button 15 by a pendulum support plate 31 which is fixed to the mounting portion 27 with a screw 30.
It is installed vertically on the inner surface. The pendulum support plate 31 has an opening 32 through which the pendulum body 16 is inserted, and an opening 32 through which the pendulum body 16 is inserted.
A pivot support 34 for receiving a pivot 33 of No. 6 is formed. In this embodiment, the shaft support 34 is formed in a groove shape, and has a rib 35 protruding from the inner surface of the push button 15.
This prevents the pivot 33 from coming off. A spring receiving portion 36 is formed at the upper end of the pendulum body 16, and the spring body 28 is compressed and held between the supporting portion 29 and the spring receiving portion 36. Therefore, the pendulum body 16 is tilted regardless of the tilted state of the push button 15.
protrudingly supported in a direction perpendicular to the push button 15;
When the pendulum body 16 rotates, a force is applied to return it to its initial state. The lower end of the pendulum body 16 has a triangular shape, and is formed to reduce frictional resistance. The hanging direction of the pendulum body 16 is directed toward the support portion 18 of the switch body 14. Therefore, when the push button 15 is not pressed, the pendulum body 16 faces one of the first pressing part 20 and the second pressing part 21, and more precisely, it faces either of the substantially chevron-shaped parts 19. It is located opposite the slope of the

The operation of the push button switch device 11 will be explained based on FIGS. 2 to 5. When the push button 15 is pressed from the state in which the push button switch device 11 is initially positioned as shown in FIGS. 2 and 4, the pendulum body 16 is guided by the inclined surface of the substantially chevron-shaped portion 19 and is positioned as shown in FIG. 3. As shown in FIG. 5, the switch body 14 is rotated and tilted, and the second pressing portion 21 is pressed to operate the operating body 13, thereby switching the switch body 14. Thereafter, when the pressure on the push button 15 is released, the push button 15 is returned to its original position by the spring body 25, and the pendulum body 16 also returns to its initial hanging state and at the same time climbs over the substantially chevron-shaped portion 19, as shown in FIG. It is located opposite to the first pressing part 20 as shown in FIG. Next, when the push button 15 is pressed again, the second
The state is switched to the state shown in the figure and FIG.

Note that the present invention is not limited to the above-mentioned embodiments, and the structures and mounting structures of the seesaw type operating body 13, push button 15, and pendulum body 16 can be modified in various ways without changing the gist thereof. . For example, the spring body 25 is coiled, but a torsion spring may be incorporated in the pivot 22 portion. Further, the return of the push button 15 is possible even without the spring body 25 by the pendulum body 16.
It is also restored by the restoring force of.

Further, if the push button switch device 11 is not required, the mounting recess 12 needs to be closed with a separate member. At this time, if the stopper 24 of the push button 15 is formed long enough to abut the mounting recess 12 as shown by the dotted line in FIG. 2, the push button 15 can be used to close the fitting. Further, in order to prevent the push button 15 from wobbling, a screw 40 can be screwed into the stopper 24.

(f) Effects of the invention This invention has a simple structure such as a pendulum attached to the push button, and allows the switch body to be changed by pressing the seesaw-type operating body, and various models with good operability can be used.
