Further, the width direction of the seat body 3 is perpendicular to the direction of the front-rear direction of the seat body 30, and is the direction in which the paper surface advances in the side view of Fig. 4. Therefore, the width direction of the seat body 3 is the same as the width direction of the baby shaker 1 described above. Hereinafter, in the specification, the front-rear direction refers to the front-rear direction of the seat body (the front-rear direction of the baby shaker). The so-called width direction refers to the width direction 16 of the seat body (the width direction of the baby shaker). First of all. The fixed portion 41 is clarified. In the present embodiment, the fixing portion 41 is formed in a flat plate shape. The fixing portion 41 is horizontally set to the side of the strip 2 while the side 1 is connected. In the present embodiment, an example in which the fixing portion 41 and the side plate 2 are formed separately is shown, but the body may be formed. Yu Guzhen. A pair of rocking members 62 (Fig. 5) disposed on the P41 in the width direction of the seat body 3' are disposed along the front and rear directions of the pair of the rocking members 62. a pair of rocking members (ie, a total of four rocking members) (simplified. Further, the rocking member support base 42 is disposed on each of the rocking members 623 on the upper surface of the fixing portion 41, and the D42U rocking shaft 61 is supported by each of the rocking members. Each of the rocking members & is supported by a bearing (not shown) such that the rocking shaft 61' can be rocked about the rocking (10). The rocking pumping 61 is inclined in the width direction from the vertical direction toward the seat body 3 (10), and the upper end 61a of the rocking shaft 61 is rocked. The lower end 6lb of the rocker_ is disposed in the width direction of the seat body. FIG. 1 . When the force is applied to the rocking member, the rocking member 62 may extend in the width direction of the seat body 3 by gravity. A long groove 62b extending along the longitudinal direction of the whip 62 is provided on the upper surface of the front end portion 62a of each of the wobble members 62. A spherical body 63 is disposed in the long groove (4). The spherical body 63 is free to move in the longitudinal direction of the rocking member by rotating along the long groove. Further, the four rocking members 62 and the four rocking member supporting tables are similar to the four vibration pumping plates 61, respectively, which are formed of a butterfly size and a phase (four) shape. Hereinafter, the movable portion 51 will be described in further detail. 17 1361056 As shown in Fig. 5, the movable portion 51 has a flat movable portion base 51a, and is provided at a position corresponding to the long groove 62b of the distal end portion 62a of each of the swinging members 62 on the lower surface of the movable portion base 51a. A receiving base 52 that protrudes downward. A hole 52a for receiving the ball-shaped body 63 is provided on the end surface of the receiving base 52 opposed to the long groove 62b. By arranging the spherical body 63 between the hole 52a of the receiving base 52 and the long groove 62b of the whip 62, the movable portion 52 is slidably supported by the front end portion 62a of the whip 62. Further, the end surface of the receiving base 52 does not contact the upper surface of the outer peripheral portion of the long groove 62b (Fig. 5). Therefore, the movable portion 51 can smoothly slide with respect to the front end portion 106 2a of the whip 62 with the spherical body oscillating in the rotational movement in the long groove 62b. Further, as shown in Figs. 5 and 6, when the rocking member extends in the width direction of the seat body 30, the spherical body 63 is disposed on the innermost side in the width direction of the long groove 62b (the axis of the rocking shaft 61). Further, as shown in Figs. 4 and 5, a guide plate 53 extending in the front-rear direction of the seat body 3A is provided at the center in the width direction of the lower surface of the movable portion base 51a. Further, in the fixing portion 41, two restricting members 43 having a substantially U-shaped shape with a space interposed therebetween are provided along the front-rear direction of the seat main body 3, and the restricting member 43 is extended upward and the guide plate 53 is caught. By the engagement of the restriction member phantom and the guide plate 53, the movement of the movable portion 51 with respect to the fixed portion in the width direction can be restricted. 20 Further, as shown in Fig. 4, near the lower end of the guide plate 53 The guide opening 53a extending in the front-rear direction is provided. On the other hand, the limiting member is provided with a limiting shaft 43a extending through the guiding opening 仏 and the two ends are connected to both sides of the guiding opening 53a. The restricting member 43 can prevent the movable portion 51 from being "detached" by the fixed portion by the guide opening 53a and the restricting shaft 43a'. Further, on the upper surface of the movable portion base 51a, a support material corresponding to the arrangement position of each of the receiving bases 52 is provided. As shown in Fig. 4, each of the support portions 54 is engaged with the receiving portion w projecting from the lower surface of the seat portion 31 of the seat body 30, and the support portion 54 is engaged with the receiving portion 31a to be movable. The portion 51 5 supports the seat body 3〇 from below. Further, in the present embodiment, the movable portion 51 is formed separately from the seat body 3', but the movable portion 51 may be formed integrally with the seat portion 31_ of the seat body 3''. That is, the guide plate 53 is provided on the lower surface of the seat portion 31 of the seat body 3〇, and the seat portion 31a of the seat portion 31 of the seat body 3 is configured in the same manner as the above-described receiving frame 52, so that the seat body is provided. The seat portion 31 of the 30 is directly supported by the rocking member 62. This rocking mechanism 40 has a flat shape having a thin thickness as shown in Figs. 4 to 6 . Therefore, the rocking mechanism 40 can be disposed below the seat body 3〇, and the entire baby shaker 1 can be miniaturized. 15 Hereinafter, the action of the rocking mechanism 40 of the above configuration will be described. The above-described rocking shaft 61 is disposed in an inclined manner, and its upper end 61a is located outside the lower end 61b of the seat body 30 in the width direction. Therefore, when the swinging member 62 extends in the width direction of the seat main body 3〇 shown by the solid line in FIG. 6, it is disposed at the lowest position, and is sequentially placed at a height of 20 as the position is swung toward both sides. position. Therefore, once the rocking member 62 is shaken, the rocking member 62 is periodically rocked toward both sides centering on the width direction of the seat body 3'''''''''''' Further, as shown in Fig. 6, the rocking member 62 is rocked, and the position of the front end portion 62a of the rocking member 62 is moved inward in the width direction of the seat body 30. But 19 1361056

The position does not move in the width direction of the main body 30 in the width direction of the main body 30. In this way, the movable part suppresses the movement of the brother and the question. Since the front end portion 62a of the rocking member 62 is moved to the inner side, the receiving table 52 is moved in the width direction of the seat body 30, and the rear direction is smoothly and periodically reciprocated. The thickness of the rocking mechanism 4 (10) can be reduced only when the inclination angle Θ- of the front body 6! of the seat body 3 is reduced. So you can not make the baby shaker! The overall size is adjusted to be younger, and the rocker 62 is periodically shaken by the principle of a so-called horizontal pendulum. Therefore, not only is the length of the long direction of the rocking member 62 longened, but also the rocking member can be shaken by making the inclination angle Θ of the width direction of the rocking shaft 61 toward the width direction of the seat body 3〇 small. The cycle becomes longer. Also, shake the 15 most appropriate shaking cycle. Further, the restricting member 43 has a restricting shaft 43a for penetrating the guide opening 53a of the guide plate 53.

Therefore, the period of the reciprocating movement of the movable portion 改变 can be changed by changing the shape of the curved trajectory 93 or the like. At this time, in order to lengthen the period in which the movable portion 51 reciprocates, the curved shape of the curved rail 93 can be made gentle, so that the outer shape of the rocking mechanism 9A is not increased. Further, the special wheel 96 has a flange portion %a (secondary view) in which the width direction (four) side is engaged with the inner side surface 93c of the curved rail 93, and the wheel % cannot move in the width direction with respect to the wheel shaft 97. Further, the side wall 91 is provided to cover the top portion W above the five curved rails 93, so that the ash turn f-tracks 93 can be prevented from being stacked. Therefore, not only the movement of the movable portion 51 in the width direction of the seat body 30 but also the movement can be restricted. The portion 51 can smoothly reciprocate in the front-rear direction of the seat body 30. Further, the guide opening 94 is provided in the side wall 91, and the end portion 97a of the wheel axis π is disposed in the vicinity of the upper edge portion 94a of the guide opening 94. Therefore, when the wheel % is to be detached from the 10 f curved rail 93, the end portion 97a comes into contact with the upper edge portion % of the guide opening σ94. Thereby, it is possible to prevent the wheel 96 from being detached from the tube track %, and to prevent the movable portion 脱离 from being detached from the fixed portion W. Further, the side edge portion 94a of the whistle guide opening 94 at the end of the wheel axle is in contact with each other, thereby preventing the movable portion 51 from excessively moving in the front-rear direction. In the reciprocating movement of the fixed seat body 30, the torsion bar 98a projecting from the rocking mechanism 9A toward the rear side in the rear direction is rotated by 9 turns. The lock member 99 is rocked upward via the lock shaft 第 (Fig. 14). Thereby, the wheel (4) enters the lock groove 99a of the lock member 99, and the movement of the wheel shaft 97 toward the front-rear direction of the seat body 3 is restricted, and the seat body 30 is fixed with respect to the side plate 2''. As described above, according to the present embodiment, the wheel 96 of the movable portion 51 is disposed on the test track 93 of the fixed portion 41. Therefore, the movable portion can reciprocate relative to the fixed portion 41 by gravity. Moreover, the rocking mechanism 90 has a flat outer shape with a small thickness, and the rocking mechanism 90 can be disposed under the seat body 30, so that the baby shaker can be changed to the shape of the curved roadway 93 by changing the shape of the curved roadway 93. The reciprocating movement period of the movable portion 51 is made longer without increasing the outer shape of the swing mechanism 90. Thereby, the reciprocating movement of the seat body 30 can be adjusted to the optimum shaking period for the child. Further, by the end portion 97a of the wheel axle 97 being engaged with the guide opening 94 of the side wall 91, the movable portion 51 can be prevented from being detached from the fixed portion 41 and the fixed portion 41 of the movable portion 5o opposed to excessively moved. Further, the wheel 96 has a flange portion 96a that is engaged with the inner side surface 93c of the curved rail 93 on the inner side in the width direction, and is not movable in the width direction with respect to the wheel axle. Further, the side wall 91 is provided with a top portion 91a for covering the upper side of the curved rail. Thereby, the movement of the movable portion 51 in the width direction of the seat body 3〇 can be restricted, and the movable portion 51 can smoothly reciprocate in the front-rear direction of the seat body 3〇. Further, by rotating the lock shaft 98, the lock groove 993 of the lock member 99 is held by the wheel shaft 97 in the front-rear direction, and the movement of the movable portion 51 in the front-rear direction is restricted. Thereby, the seat body 3〇 can be fixed relative to the side plate 2〇. Further, in the present embodiment, the display fixing portion 41 has a lock shaft 98 that is rotatable in the front-rear direction of the seat body 30 and is fixed to the lock shaft 2〇98, and has a wheel shaft 97 disposed on the wheel %. The lock element 99 of the lock groove 99& which is engaged with the wheel axle 97, and the lock element 99, can restrict the movement of the wheel axle 97 in the front-rear direction of the seat body 3〇 by rotating the lock shaft. For example, it is not limited to this. As shown in FIGS. 15A and 15B, the fixing portion 41 may have the following members, that is, the lock shaft 1〇2, which extends in the rearward direction of the body 36 of the seat 36 and is movable in the front-rear direction; The element 99 is movable in the up and down direction and has a lock groove 99a disposed below the wheel axle 97 of the wheel 96 for engaging with the wheel axle 97; the connecting rod 1〇3 is rotatably The components are respectively connected to the lock shaft 102 and the lock member 99; and the 5-member member 101 is disposed on the fixed portion base 92 of the fixed portion 41 for restricting the movement of the lock member 99 in the front-rear direction.

In the present modification of the configuration, the lock shaft 1〇2 is moved such that the connection point 1〇4 of the lock shaft 1〇2 and the connecting rod 103 is away from the connection point 105 of the lock member 99 and the connecting rod 1〇3 in the front-rear direction. Along with this, the lock member 99 moves downward. In the other direction, the lock shaft 102 is moved such that the connection point of the lock shaft 1〇2 and the connecting rod 1〇3 is close to the connection point of the lock element and the connecting rod (10) in the front-rear direction, and the lock element 99 will face Move above. Then, when the lock member 99 is moved upward, the 'wheel (four) enters the lock groove of the lock member 99' to restrict the movement of the wheel shaft 97 in the front-rear direction. 15

When the lock shaft 102 is moved toward the rear side, the navigation member 99 is moved downward, and as shown in the drawing, when the lock (4) 2 is moved forward, the lock member 99 is moved upward. 20 And as shown in the 15th turn, when the lock element 99 moves upwards ^ turns the wheel (four) toward the (four), making the light %
