Since lateral vibration of the inner cutter 2 occurs due to the connection between the inner cutter 2 and the drive element 6, an appropriate gap is provided between the outer cutter 4 and the upper inner surface of the outer cutter frame 3. It is provided. Therefore, this gap prevents deformation of the outer cutter 4 due to lateral vibration of the inner cutter 2, uneven wear, and generation of abnormal noise. In addition, in the actual shaving condition, a shaving load is applied in the P direction shown in FIG.
An intersection part E is provided between the upper surface of the inner cutter 2 and the lower surface of the inner cutter 2. Therefore, the lower surface of the inner cutter 2 is prevented from protruding from the upper surface of the outer cutter frame 3 when the inner cutter 2 is pushed upwardly. Most of the beard debris during shaving falls below the inner cutter 2, but some of the beard debris is introduced into the slit 20 through the surface of the outer cutter 4 through the gap 2, and is further introduced into the slit 20. Tahige calendar is slit 20 and slope 22
It passes along the top and is discharged downward. Further, the beard shoulder on the upper surface of the outer cutter frame 3 is automatically removed by the comb-shaped slit 20 by the vibration of the inner cutter 2, so that the beard shoulder does not accumulate in the gap. Note that 23 is a protective cap that covers the outer cutter 4 and the outer cutter frame 3. Furthermore, the shape of the lower part of the slit 20 is a curved surface as shown in FIG. 2, which facilitates the removal and cleaning of hair debris adhering to the surface of the slit 20. In addition, the slits 2 at both ends of the outer blade frame 3
The length in the vertical direction is made shorter by 0. Therefore, the hair that has accumulated inside is likely to spill out into the gap between the outer cutter 4 and the outer cutter frame 3 at both ends where the outer cutter 4 is attached to the outer cutter frame 3, reducing the area of the face surface 22 in the slit 20. By doing so, the amount of adhesion of beard debris can be reduced and cleaning work becomes easier. On the contrary, the slit 20 at the center of the outer cutter frame 3 is made longer than the length in the vertical direction of the slits 20 at both ends.
As mentioned above, the outer cutter frame 3 is formed with the aim of producing a raised effect when the outer cutter frame 3 is brought into contact with the skin. A drive block B, which is a drive unit for driving the inner cutter 2, has an eccentric balancer 12 attached eccentrically to a metal shaft 11 of a motor 10 disposed in the lower portion of the housing 1.

By setting the insulation distance b between the upper end of the insulating member 24 provided at the lower part of the eccentric 10 balancer 12 and the upper surface of the motor 10 to be four or more ribs, the through window 27 of the trimmer 9 formed in the housing 1 and the eccentric shaft 13 are set. Insulation can be ensured by setting the insulation distance a to the eccentric balancer 12 to be 4 degrees or more, so that the insulation effect is good, the electrical insulation safety is increased, and the appliance can be used with peace of mind. Furthermore, since insulation can be ensured without increasing the thickness of the housing 1, it can be manufactured in a small size. 6 to 8 show a structure for attaching and detaching the housing 1 and the instrument plug 32, and the bottom surface of the housing 1 is formed with an elliptical hole portion 28 having a closed lower surface. A pair of terminal pins 29 are provided in the barrier hole portion 28 to project downward, and both terminal pins 29 of the barrier hole portion 28 are provided with a pair of terminal pins 29 projecting downward.
, 29, a clip pin 30 that is movable in the lateral direction is protrudingly provided approximately at the center of the inner wall surface. This clip pin 30 is biased by a coil spring 31 in the housing lb so that its tip protrudes into the opening 28. The instrument plug 32 has a shape that substantially corresponds to the shape of the barrier hole 28, and has a pair of plug receiving blades 33 formed therein to be connected to the terminal pin 29 in a ferrous manner. Recesses 34 having a substantially triangular cross section corresponding to the shape of the tip of the clip pin 30 are provided on both sides of the instrument plug 32 at locations corresponding to the clip pins 30 . FIG. 6 shows the housing 1 and the instrument plug 32 in a state in which the clip pin 30 and the recess 34 are iron-coupled to form a so-called lock. When the instrument plug 32 is attached or removed, the click pin 30 is pushed against the coil spring 31 by the distal end surface of the instrument plug 32 and the slope of the recess 34. In this way, the locking click pin 3 is placed in the center between the terminal pins 29.

Note that the surface of the housing la where the engagement protrusion 35 is provided and the surface below that where the dimple portion 7 is provided are defined by the protective cap 23 when the outer cutter frame 3 is covered with the protective cap 23.
The surface on which the dimple portion 7 is provided is one step higher so that the outer surface of the housing la and the surface of the housing la are substantially flush with each other.
A protective cap 23 is also placed in the upper center of the other housing lb.
A rectangular engagement convex portion 36 for engagement is provided in a protruding manner. On the other hand, as shown in FIG. 4, the elastic protective cap 23 is provided with an engaging recess 37 corresponding to the engaging protrusion 35 and an engaging recess 38 corresponding to the engaging protrusion 36 at the lower part of its inner surface. It is being When the protective cap 23 is attached, the protective cap 23 is attached to the engaging protrusion 35 and the engaging protrusion 3 of the housing 1.
Up to 6, the outer cutter frame 3 and the upper part of the housing 1 guide it smoothly and the load is small and it can be inserted, and when the lower end of the protective cap 23 comes to the engagement protrusion 35 and the engagement protrusion 36, the load suddenly increases. becomes larger, the engagement protrusion 35 is engaged with the engagement recess 37, the engagement protrusion 36 is engaged with the engagement recess 38, and the protective cap 23 is attached to the housing 1. When the relationship between the load F and the stroke S when the protective cap 23 is attached is graphed as shown in FIG. 5, the characteristic curve shows a steep sacrifice in the rise. This sudden rise indicates that the protective cap 23 has a good clickability (feel) when attached, and is what is called a snap. Conversely, if the rise of the characteristic curve is slow, the feel will be poor. When removing the protective cap 23 from the housing 1, the protective cap 23 can be removed from the engaging portion by pinching the side walls 39 on both sides and using elasticity to widen the gap. By the way, in the case where the outer cutter frame 3 is formed with a protrusion for engaging with the protective cap 23, when the protective cap 23 is pulled, the outer cutter frame 3 also comes off. Since the protrusion 36 is provided on the housing 1, the outer cutter frame 3 will not come off even if the protective cap 23 is pulled. Furthermore, if the mating portion of the protective cap 23 is a protruding protrusion, the protrusion will rub against the outer cutter frame 3 when the protective cap 23 is attached or detached, causing paint peeling. Since the engaging portion is a recessed engaging portion consisting of an engaging recess 37 and a sub-recess recess 38, peeling of the paint does not occur.
As described above, the present invention includes forming a comb-shaped slit vertically through a rib in the upper end of at least one of the outer cutter frames to which both ends of the outer cutter, which has an arcuate cross section and corresponds to the inner cutter, are attached. Since the surface of the outer cutter frame facing this slit is tilted downward to form a forehead slope that reaches the outer surface of the outer cutter frame, the beard debris that is generated when shaving and flies to the side can be removed from the slit and Enoki slope. Since it is discharged to the outside through
As a result, the outer cutter does not deform even when the inner cutter oscillates laterally, extending its service life, maintaining good sharpness, and reducing noise.Furthermore, the slit makes the outer cutter look larger and generates more power. This has the effect of increasing the feeling of fullness.
