Generally, a seat bag 1 as shown in FIG.
A configuration is known in which a head rest 2 is attached to the upper end portion and this head rest 2 is detachably supported on the upper end portion of the seat bag 1. In this case, as shown in FIG. 4, a pair of approximately cylindrical stays 3, 3, for example, are provided protruding from the lower end portion of the headrest 2. Also,
As shown in FIG. 5, a pair of stay guides 5, 5 made of synthetic resin are embedded in the upper end portion of the seat bag 1, and are provided with insertion holes 4 through which the stays 3 are inserted. A lock spring 6 is attached to the upper end portion of each of these stay guides 5, and a lock release knob 7 is attached to the tip end of the lock spring 6. This lock spring 6 is movably provided from an extended position where it extends to the inside of the insertion hole 4 to a pushed-out position where it is pushed out to the outside of the insertion hole 4 by operating the lock release knob 7. It is normally held in the extended position by spring force. Furthermore, engagement grooves 8, 8 are formed in the upper end portions of the pair of stays 3, 3 of the headrest 2 at portions corresponding to the lock springs 6, 6 of the stay guides 5, 5. Then, move the headrest 2 to a predetermined insertion position in the insertion holes 4, 4 of the stay guides 5, 5.
By inserting the stays 3, 3, the lock springs 6, 6 are automatically engaged in the engagement grooves 8, 8 of the stays 3, 3, and the headrest 2 is locked in the installed state. There is. In addition, by operating the lock release knob 7 to move the lock springs 6, 6 to the pushed-out position to the outside of the insertion hole 4, the engagement grooves 8, 8 of the stays 3, 3 and the lock spring 6 , 6 to release the lock of the headrest 2, and the stays 3, 3 of the headrest 2 can be pulled out from the insertion holes 4, 4 of the stay guides 5, 5.

In the conventional structure, the insertion holes 4, 4 of the stay guides 5, 5 embedded in the upper end portion of the seat bag 1 were approximately circular as shown in FIG. Therefore, if the diameter of the insertion hole 4 is too large, there is a problem in that the stay 3 wobbles when the headrest 2 is attached. Furthermore, if the hole diameter of the insertion hole 4 is too small, it becomes difficult to insert the stay 3 into the insertion hole 4 or to pull out the stay 3 from the insertion hole 4, making it troublesome to attach and detach the headrest 2. I had a serious problem. Therefore, the outer diameter dimension of the stay 3 of the head rest 2 and the hole diameter dimension of the insertion hole 4 of the stay guide 5 must be manufactured with high accuracy, and there is a problem that the manufacturing thereof becomes troublesome.

FIGS. 1 and 2 show an embodiment of this invention. In addition, in Figures 1 and 2,
The same parts as in FIGS. 3 to 6 are given the same reference numerals, and their explanations will be omitted. That is, in this embodiment, the stay 3 protruding from the head rest 2 is formed into a substantially cylindrical shape, and the insertion hole 11 in the stay guide 5 is formed into a substantially cylindrical shape.
The width dimension a in the front-rear direction of the stay guide 5 is set to be approximately equal to the outer diameter dimension s of the stay 3, and the stay guide 5
By setting the horizontal width dimension b of the insertion hole 11 to be larger than the outer diameter dimension s of the stay 3, the stay guide 5
The insertion hole 11 is formed in the shape of a horizontally elongated hole, and an engagement groove 8 is formed on the circumferential surface of the stay 3, and the stay 3 is engaged with the engagement groove 8 to prevent the stay 3 from sliding. A lock spring 6 that presses one side in the longitudinal direction of the cross section of the insertion hole 11 in such a state is installed near the joint portion of the stay guide 5 with the head rest 2, and furthermore, the lock spring 6 is installed to allow the stay 3 to slide. A lock release member 7 is provided to displace the lock.
In this case, the lock spring 6 of the stay guide 5 is disposed on one end side of the elongated insertion hole 11, and the lock release knob 7 is disposed on the back side of the seat bag 1. When the headrest 2 is attached, the stay 3 of the headrest 2 is inserted to a predetermined insertion position in the insertion hole 4 of the stay guide 5.
The lock spring 6 is automatically engaged in the engagement groove 8 of the stay 3, and the headrest 2 is locked in the installed state. The head rest 2 is held in a state where it is pressed against the other end side of the head rest 11, so that lateral wobbling of the head rest 2 is suppressed.

Therefore, in the case of the structure described above, the longitudinal width dimension a of the insertion hole 11 in the stay guide 5 is set to be approximately equal to the outer diameter dimension s of the stay 3 of the headrest 2, and the insertion hole 11 of the stay guide 5 The horizontal width dimension b of the stay guide 5 is set larger than the outer diameter dimension s of the stay 3, and the insertion hole 11 of the stay guide 5 is formed in the shape of a horizontally elongated hole. 3 can be absorbed by the play in the lateral width dimension b of the insertion hole 11 of the stay guide 5. Therefore, the stay 3 is inserted into the insertion hole 11 of the stay guide 5.
The stay 3 can be easily inserted or pulled out from the insertion hole 11, and the operation of attaching and detaching the headrest 2 can be facilitated. Furthermore, since it is not necessary to manufacture the stay 3 of the headrest 2, the insertion hole 11 of the stay guide 5, etc. with particular precision, the manufacture of these can be made easier than in the past. In addition, since the longitudinal width dimension a of the insertion hole 11 in the stay guide 5 is set to be approximately equal to the outer diameter dimension s of the stay 3 of the headrest 2, it is possible to reliably prevent the headrest 2 from shaking in the longitudinal direction while the vehicle is running. can do. Furthermore, when installing the headrest 2, by inserting the stay 3 of the headrest 2 to a predetermined insertion position in the insertion hole 4 of the stay guide 5,
The lock spring 6 is automatically engaged in the engagement groove 8 of the stay 3, and the headrest 2 is locked in the installed state. The stay 3 is held in a state where it is pressed against the other end of the headrest 2, and the lateral wobbling of the headrest 2 is suppressed, so that it is possible to prevent the stay 3 from wobbling when the headrest 2 is installed. This can be prevented even more effectively. Also, since the lock spring 6 is attached to the upper end position of the stay guide 5, the lock spring 6 engages the stay 3 in the engagement groove 8 of the stay 3, and the stay 3 is engaged by the lock spring 6. The distance between the headrest 2 and the head rest 2 can be made relatively short. Therefore, rattling of the headrest 2 can be more effectively prevented.
