のとなる。The movement of the cam follower 3 is transmitted to the slider 52 through the drive shaft 30 which is integral with the cam follower 3 and the connecting rods 60 and 61, and the axial reciprocating linear movement is the reciprocating sliding movement of the slider 52. The rack and pinion engagement between the turntable 55 and the holder 51 causes the turntable 55 to reciprocate. Further, the reciprocating rotational movement of the cam follower 3 is directly the reciprocating rotational movement of the slider 52 and the holder 51. Therefore,
As shown in FIG. 10, the brush base 56 attached to the rotary base 55 pivotally supported by the pin 53 of the slider 52 has an axial reciprocating linear motion of the handle 50 (stroke S = 2 (e 1
+ E 2 )), the reciprocating rotary motion of the handle 50 about its axis, and the reciprocating rotary motion of the pin 53 about its axis are combined. When such a movement is performed by the brush bundle 57, the brush cleaning area is widened, and the brush bundle 57 does not stay in the same place for a long time. Does not happen. The movement of the brush bundle 57 seen from the front at this time is O-shaped as shown in FIG. 10B, except for the reciprocating rotational motion component of the pin 53 about the axis.

1 receives only the reciprocating rotary motion of the handle 50 around the shaft, and the slider 52 receives both the axial reciprocating linear motion and the axial reciprocating motion of the handle 50.
That is, since the slider 52 performs only a reciprocating linear motion with respect to the holder 51, the reciprocating rotational motion of the brush bundle 57 around the protruding axis direction is easily generated by using the rack and pinion or the like as described above. can do.

与える。When the rotating body 1 is rotated in the counterclockwise direction indicated by the arrow in FIG. 7A, only the rotating cam portion 22 is eccentric with respect to the shaft 40 as described above, and the reciprocating cam portion 21. 8 is concentric with the shaft 40, the reciprocating cam portion 21 simply rotates within the first follower portion 31 of the cam follower 3 as shown in FIG. Rotating cam portion 22 in contact
Causes the cam follower 3 to make a reciprocating rotational movement within a range corresponding to the inclination θ 1 of the inclined surface 24 in the axial direction with the rotation. The movement of the cam follower 3 gives the brush bundle 57 only a reciprocating rotational movement about the axis of the handle 50, which is a rolling polish.

与えることがない。The range of the reciprocal rotary motion in the latter case of rolling polishing is made smaller than the range of the reciprocal rotary motion in the former case of complex motion.
This is because the gums are not damaged during rolling polishing, but the same may be used. In the former case of performing the combined movement, the rotation of the brush bundle 57 and the reciprocating linear movement of the handle 50 in the longitudinal direction are added. Therefore, the reciprocating rotary motion component around the shaft of the handle 50 is large. However, since the brush bundle 57 does not flip up a certain position of the gum portion, the gum portion is not damaged.

る。The connecting spring 62 shown in FIG. 5 (c) is used in place of the connecting rod 61. In the toothbrush attachment 5 using the connecting spring 62 in place of the connecting rod 61, the reciprocating rotational movement is performed. Since the component is absorbed by the connecting spring 62, only the reciprocating linear motion is transmitted to the slider 52, and at this time, the brush bundle 57 performs the reciprocating linear motion and the reciprocating rotary motion about the axis of the pin 53. Of course, since the conventional toothbrush attachment 5 provided conventionally can be used, it is possible to perform tooth brushing in various operations from the single main body 5.

束５７に行わせる。In the embodiment shown in FIG. 11, an eccentric portion 15 having an eccentricity amount of e 5 is formed at the base of the shaft portion 11 having an eccentricity amount of e 1 of the rotating body 1, and the outer periphery of the tip end portion of the shaft portion 11 is formed. Assuming that the cam 2 to be arranged has an eccentricity amount e 2 that is equal to the eccentricity amount e 1 of the shaft portion 11, the upper and lower inner edges of the first follower portion 31 of the cam follower 3 are set to the eccentric portion 15 and the second follower portion 32 is set. The left and right inner edges are in contact with the cam 2. Then, when the rotating body 1 rotates in one direction, as shown in FIG.
Since the eccentric amount with respect to 0 is set to e 1 + e 2 , the cam follower 3 has a stroke S (S = 2) corresponding to the eccentric amount e 5 of the eccentric portion 15 received by the first follower portion 31.
e 5 ), a vertical reciprocating linear motion and a reciprocating rotary motion corresponding to the eccentric amount e 1 + e 2 of the cam 2 received by the second follower portion 32 are combined to draw an elliptical locus, Similar to the above embodiment, the brush bundle 57 is caused to perform the movement shown in FIG.

除くとＳ字を描くものとなる。The embodiment shown in FIG. 13 shows that the operation is not switched depending on the rotation direction of the motor 42. The eccentric portion 15 is provided on the shaft portion 11 of the rotating body 1 and the eccentric rotation is performed. The moving cam portion 16 is provided so that the eccentric portion 15 causes the cam follower 3 and the drive shaft 30 to reciprocate linearly, and the rotating cam portion 16 causes the cam follower 3 and the drive shaft 30 to move.
Is performing a reciprocating rotary motion. Also in this one,
The brush bundle 57 can be caused to perform the movement shown in FIG. In addition, the eccentric direction of the eccentric portion 15 and the rotating cam portion 16 is shifted by 90 ° to shift the phases of the reciprocating linear motion and the reciprocating rotational motion, and as shown in FIG. If the dead point of the movement and the dead point of the reciprocating rotary movement are made to coincide with each other, the movement seen from the front of the brush bundle 57 is as shown in FIG.
As shown in FIG. 5, an S-shape is drawn when the reciprocating rotary motion component around the axis of the pin 53 is removed.

Since the eccentric component of the rotating cam portion is canceled every 90 °, and the cam follower 3 can perform two reciprocating rotational movements during one rotation of the rotating body 1, as shown in FIG. 16 (b). In addition, the movement of the brush bundle 57 when viewed from the front can be made to draw eight characters when the reciprocating rotary motion component around the axis of the pin 53 is removed.
