As shown in FIG. 3, the band member 3 constituting the mounting portion 1a is thinly formed over substantially the entire length thereof in order to enhance flexibility, and the tongue piece 5 is also made of the same. In order to enhance flexibility and to smoothly fit the locking projections 4, the locking projections 4 of the band 3 are formed to be thin like the band 3. The portion where it is formed is formed to be slightly thick in order to increase the support strength of the locking projection 4.

Further, as shown in FIG. 3, the locking projection 4 is formed on the tongue piece 5 such that the base end portion 4 a has a small diameter and the tip end portion 4 b has a large diameter. The engagement hole 5a is for facilitating passage of the fitting portion 5b having substantially the same inner diameter as the base end portion 4a and the large-diameter tip portion 4b of the locking projection 4 in the fitting portion 5b. The enlarged diameter portion 5c is used.

The gripping portion 1 b includes a pair of holding pieces 6, a pivot shaft 7 connecting the pair of holding pieces 6 swingably at an intermediate portion thereof, and the pair of holding pieces 6. It is configured by a torsion spring 8 which elastically springs in a direction in which the sandwiching portions 6a formed at one end portions are brought into contact with each other.

Further, in the present embodiment, the connecting portion 1c is formed in a coil shape so as to be expandable and contractible, and is integrally formed at an end portion of the strip 3 on the side where the locking projection 4 is provided. And the grip portion 1b is rotatably connected at the other end.

That is, as shown in FIG. 3, one of the pair of holding pieces 6 constituting the grip portion 1b is integrally provided with a locking projection 9 having a large diameter at its tip portion 9a, Further, a locking hole 10 having an inner diameter slightly smaller than the outer diameter of the tip 9a of the locking projection 9 is formed at the other end of the connecting portion 1c, and the tip of the locking projection 9 is formed. 9a pushes the locking hole 10 wide so that the locking projection 9 is fitted into the locking hole 10 so that the grip portion 1b is attached to one end of the connecting portion 1c. It is rotatably connected with 9 as the center.

Next, a method of using the knee rest locking tool 1 according to the present embodiment thus configured will be described. First, the band 3 of the mounting portion 1a is wrapped around the pole 2a of the stroller 2, and The locking projection 5 provided at the other end is pushed into the locking hole 5a of the tongue piece 5 provided at one end of the band 3, and the locking projection 4 is fitted into the locking hole 5a. By doing so, as shown by the chain line in FIG. 3, both ends of the strip 3 are connected to each other, and the mounting portion 1a is mounted so as to surround the pole 2a.

According to the procedure described above, the knee rest locking tool 1 according to the present embodiment is attached to the pole 2a. By performing the attaching operation on the poles 2a on both sides of the stroller 2, the present embodiment is provided. A pair of the related hooking fasteners 1 are attached to both sides of the stroller 2.
