中心方向に力が作用するため中心部が盛り上る。(Background Art) In reciprocating electric shavers, the inner blades are generally connected and supported by an inner blade base made of synthetic resin. This is because, for example, when connecting and supporting inner blades made of die-cast aluminum, metal pipes, etc., the inner blades are stacked heavily, which increases vibration and increases the load when driving the inner blades. However, in electric shavers that use dry batteries or storage batteries, the battery quickly discharges and becomes unusable. When locking the inner cutter to the part, an m-th joint part is required to hold it. This joint part is attached to the inner blade and integrated, and is removably locked to the drive part, or the joint is attached to the drive part and is removably locked between the inner blade and the joint. The two letters are well done. Izun
Regardless of which method is used, there is peace of mind that the inner cutter base and the joint will be locked together without any jamming. This is because noise is generated due to rattling. Accordingly, the joint and the inner blade base are locked together by bullets, etc. For example, Figures 4 (a) and (b) show the inner blade of a conventional reciprocating electric shaver. The same figure (a) is a side view with a partially cutaway cross section, and the same figure (b) J is the X-X of the bottle in the same figure.
FIG. In the figure, a plurality of inner blades 1 /
An elastic hook 3' protrudes from the inner cutter base τ supporting the inner cutter base τ, and the elastic hook 3' protrudes from the inner cutter base τ, and the hook 3' is hooked to the rib 5' of the joint 4'. At this time, the elastic hook 3' is elastically pressed in the direction of the center of the inner cutter in the reciprocating direction of the inner cutter, that is, in the direction of arrow A shown in the figure. In this case, both ends of the inner cutter base 2' (center part of the rim) bulge and deform as shown by the broken line B in the figure, causing warping, so the inner cutter does not make good contact with the outer cutter at both ends. However, there was a problem that a gap was created and the beard was pulled at 9 o'clock when shaving. This n is the centroid of the inner cutter base τ that supports the inner cutter blade 1' (cross section 2
This is because a force is applied at the we position, rather than the center of the next moment. In this example, the force is applied below the centroid in the direction of the center of the inner blade, causing the center to bulge.

１′を支持する内刃基台２′の断面積を大きくして、剛
性を高くすると良いが、内刃の重量が増加する欠点があ
つ几。Conversely, when the force acts outward from the center, both ends of the inner cutter bulge beyond the center, and a gap is created between the inner cutter and the outer cutter at the center. In order to prevent these problems, it is better to increase the cross-sectional area of the inner cutter base 2' that supports the inner cutter blade 1' to increase its rigidity, but this has the disadvantage that the weight of the inner cutter increases.

are connected to each other by a connecting rib 5, and a recess 5a is provided at the center of the connecting rib 5, and the 7% recess 5a engages with a protrusion 3a provided on the elastic hook 3. Coupling 4 #: 1'' Consists of a joint base 4a and a connecting part 4b, and the joint base 4a and the connecting part 4b are engaged by a pin 4c.The elastic hook 3 is connected to the joint base 4a and the connecting part 4b. 4a.Constructed in this way, the centroid O of the nine pairs of inner cutter bases 20 is the midpoint of the centroid of each inner cutter base 2.At this centroid 0, the return The concave portion 5a of the connecting rib 5 and the convex portion 3a of the elastic hook 3 are brought into contact with the L5 on which the force is applied.In this way, the force acts on both ends of the inner cutter 8, causing the inner cutter 8 to move in the upward direction. The bending rigidity increases.For example, when a rod is pulled from both ends and a force perpendicular to the axis is applied near the center, the rod becomes difficult to bend.This is the same phenomenon.

、しつかシと保持できる利点がある。To be sure, in this embodiment, the joint portion of the inner cutter blade l supported by the inner cutter base 2 is bent to provide a bent portion 1ae, and this bent portion 1aK is provided with a hole or slit 1b. . This is because when the inner cutter blade 1 is supported as it is in a flat plate shape, the substantial cross-sectional area of the inner cutter base 2 is reduced by the amount that the inner cutter blade 1 is inserted, and therefore the inner cutter base The rigidity of the platform 2 is reduced. In this embodiment, the area of the inner cutter base 2 is increased by the area of the bent portion 1a, and the area of the inner cutter base 2 is increased by the area of the bent portion 1a.
When molding with synthetic resin, the L hole 1b has the advantage that the resin can pass through it and be held tightly.

きくたわむことがない。FIG. 3 shows the same way as in the first embodiment, in which connecting ribs are provided on each inner cutter base, and relative to the center of the inner cutter reciprocating direction,
The connecting ribs provided at symmetrical positions are elastically attached to specific elastic hooks provided on both ends of the joint so that a force acts on them. In the second embodiment, as shown in FIG. 2, compared to the first embodiment, the inner cutter base 2 is also provided on the above-ground part of the pair of connecting parts, so that the inner cutter has high rigidity.
The inner blade 1 is also firmly supported, and even if a strong force is applied to the inner blade 1 by cutting many hairs, the inner blade 1 will not bend significantly.

, ld are provided, and the bent portions 1c and 1dK are provided with holes 1b. This hole 1b may be in the form of a slit, but
The bent portions 1c and ld protruding from the adjacent inner blades 1 are arranged so as to overlap with the recessed holes 1b provided in the bent portions 1c and ld.

。In this state, the synthetic resin is molded 1117, so the synthetic resin flows through the hole 1b and holds the inner blade 1 firmly. In this second embodiment as well, unlike the first embodiment, the substantial cross-sectional area of the inner cutter base 2 is not made large, but the inner cutter blade 1 is also held firmly and
c14 Since the inner cutter blades 1 that are in contact with each other are connected, the rigidity of the inner cutter 8 is increased. Even when the inner cutter blades 1 are pressed against the skin during shaving, the inner cutter 8 bends due to the force. This prevents a gap from forming between the inner cutter 8 and the outer cutter 9.
is pressed against the outer cutter 9, and the force is dispersed over the entire contact surface between the inner cutter 8 and the outer cutter 9, which has the effect of making the cutting edge uniform.

The inner cutter base does not generate any damage, the force is rounded, and the stiffness of the inner cutter in the direction of pushing up the inner cutter is increased.
This prevents the pressing force of the inner cutter against the outer cutter and the deformation of the inner cutter when the skin is pressed against the outer cutter, preventing gaps between the inner and outer cutters and improving cutting quality. .

Larger and more rigid. In addition, by connecting this bent part with the bent part of the adjacent inner cutter blade, high rigidity can be obtained, and as mentioned above, the gap between the inner cutter and the outer cutter can be prevented. A comfortable electric oven with no pull! 7 can be provided.
