The soft member 68 is set so that the thickness D of the portion corresponding to the apex of the convex portion (arch portion 69) of the hard plate member 67 is 3 mm to 5 mm. The inner surface of the soft member 68 is covered with a covering 73 having a smooth surface. The inner surface of the soft member 68 is covered with a covering 7 having a smooth surface.
3 because the soft member 68 is made of an elastomer and its surface has a high resistance to slipping. When the head of an infant is rubbed here, the hair of the head is the surface of the soft member 68. This is to prevent this from being attached and pulled.
According to the above embodiment, when the pair of left and right steps 6 is attached to the seat body 4, when the infant is small, the upper locking hole 18 of the multiple locking holes 18 of the support plate 15 is selected. When the engaging pieces 24 of step 6 are respectively inserted into the selected pair of upper locking holes 18 and the step 6 is slid rearward with respect to the support plate 15, the pair of front and rear engaging portions 28 is formed. The upper stage side pair of locking holes 18 are engaged with each other so as not to be removable. At this time, the stop plate 23 of step 6 is superposed on or in contact with the stop plate 16 of the support plate 15 from the front side, and the mounting hole 25 of step 6 is a support plate corresponding to the upper locking hole 18. 15 corresponds to the upper mounting hole 19.

At this time, if the pair of left and right attachment bases 36 of the handle member 7 are inserted into the insertion holes 37 at the front end of the seat 2 and fitted into the fitting recesses 38 of the support plate 15, the attachment of step 6 is performed. In addition to the mounting hole 19 on the upper stage side of the support plate 15, the hole 25 has the mounting hole 3 on the upper stage side of the mounting base portion 36 of the handle member 7.
5 also matches.
Therefore, in this state, as shown in FIG. 21, the fixture 30 is inserted from the outside into the matching mounting hole 35 of step 6, the mounting hole 19 of the support plate 15, and the mounting hole 35 of the mounting base 36. And tighten.

Therefore, the step 30 is simply stopped from being slidable with respect to the support plate 15 by the fixture 30.
The step 6 can be easily and reliably attached to the support plate 15 by using the upper locking hole 18. At this time, the handle member 7 can be easily fixed to the seat 2 or the support plate 15 by using the fixture 30 at the same time.
When the infant becomes large, the lower locking hole 18 of the plurality of locking holes 18 of the support plate 15 is selected, and the lower locking hole 18 is used, similarly to the above, Support plate 1 with fixture 30
Step 6 can be attached to 5 and Step 6 can be adapted to fit a growing infant.
The step 6 can be easily and reliably attached to the support plate 15 by adjusting it to a lower position.

Therefore, the step 6 can be adjusted up and down with respect to the seat body 4 according to the growth of the infant, and the infant seat for bicycles is used for a long time while maintaining the state in which the step 6 can be suitably used. be able to.
Further, when the headrest 5 is adjusted up and down, the fasteners 54 are loosened and the headrest 5 to the support legs 45 are moved up and down with respect to the holding cylinder portion 46, so that the concavo-convex row 50 of the support legs 45.
On the other hand, the position of the concavo-convex row 50 of the support leg 45 with which the engagement protrusion 51 of the elastic support piece 48 engages is changed in small increments up and down, and the engagement protrusion 51 of the elastic support piece 48 is changed to the support leg 45. Since the headrest 5 to the support leg 45 can be held with respect to the holding cylinder portion 46 at any position moved up and down in order to maintain the engaged state with the concavo-convex row 50, the headrest 5 to the support leg 45 can be After moving to the vertical position, the loosened fastener 54 may be tightened, and the headrest 5 can be adjusted up and down very easily and accurately. In addition, by tightening the fastener 54 after adjusting the headrest 5 up and down, the elastic support piece 48 is pressed toward the support leg 45, and the engagement protrusion 51 of the elastic support piece 48 is brought into contact with the uneven row 50 of the support leg 45. The headrest 5 through the support leg 45 are securely locked so as not to move up and down with respect to the holding cylinder portion 46 by being strongly pressed and engaged. Therefore,
The height of the headrest 5 can be adjusted with high accuracy and reliability by an extremely simple operation.

そして、ヘッドレスト5は、硬質板部材67と硬質板部材67の内面に設けられた軟質

The headrest 5 includes a hard plate member 67 and a soft member 68 provided on the inner surface of the hard plate member 67. The hard plate member 67 has an arch portion 69 that is convex toward the inner surface side in a plurality of stages. By being continuously formed, it is formed in a concavo-convex shape, and the concave portion and the convex portion are continuously formed in a plurality of steps in the vertical direction, so by the concavo-convex shape by the arch portion 69 of the hard plate member 67, The rigidity of the hard plate member 67 can be increased, and the impact caused by the fall of the bicycle,
It becomes possible to absorb and relax well by elastic deformation by the multi-stage arch portion 69, and the head of the infant can be sufficiently protected.

In addition, since the soft member 68 is provided on the inner surface of the hard plate member 67 so as to fill the recesses between the plurality of arch portions 69 on the inner surface side of the hard plate member 67, the elasticity by the arch portion 69 of the hard plate member 67 is provided. The rigidity around the recess between the arch portions 69 of the hard plate member 67 that is likely to be weakened can be increased by the soft member 68 without impairing the rigidity of the headrest, thereby effectively increasing the rigidity of the entire headrest. Protection can be made more reliably. In addition, since the soft member 68 softly contacts or abuts against the infant's head, the headrest 5 more reliably guards the infant's head and is comfortable for the infant.

Therefore, when this headrest 5 is used, even if the infant is not using a helmet, the same head protection effect as the SG standard helmet can be obtained. In addition, by using both the helmet and the headrest 5, a much better effect of protecting the head can be obtained.
Further, a cover body 8 having a pair of left and right cover portions 41 that closes the left and right openings 40 between the left and right sides of the backrest portion 3 of the seat body 4 and the left and right sides of the handle member 7 is provided.
Is supported by the seat body 4 so as to be rotatable around the horizontal axis 42, and the cover body 8 is stowed along the inner surface of the seat body 4, and the cover body 8 projects forward from the seat body 4 and a pair of left and right cover parts. 41. Since the posture can be changed to the closed posture in which the left and right openings 40 are closed at 41, when the infant is put on the bicycle infant seat 1, the cover body 8 is attached to the seat body 4 as shown in FIG. By keeping the storage posture along the inner surface, the infant can be put on the infant seat 1 for bicycle without the cover body 8 being in the way. When the infant is not put on the bicycle infant seat 1, the cover body 8 is rotated around the horizontal axis 42 in the direction of the arrow a shown in FIG. As a result, the cover body 8 protrudes forward from the seat body 4 and the pair of left and right cover portions 41 closes the left and right openings 40, so that the luggage can be placed on the seat body 4 so as not to fall, and the seat body 4 is loaded. It can be used effectively in a basket and is very convenient.
