形成される。Then, in a state where the resin material is cured to a predetermined state, a gas as a fluid is jetted inside the resin material from an arbitrary position. Then, this gas advances while pushing away the resin material substantially along the axial center portion of the resin material, and the space portion 22 is formed in the main body portion 12 by the so-called gas injection (gas injection injection molding) method. At this time, along the both sides of the long axis hinge portion 20, the outer recessed portion
Since the space portion 22 is formed, the space portion 22 grows in an acute angle (edge shape) toward the hinge portion 20, that is, toward the parting line PL of the mold, and each inner recessed portion 24 is formed. To be done.

状になる。Then, the covering portion 14 is integrally insert-formed on the outer peripheral portion of the covering portion mounting portion 16 of the main body portion 12, and the main body portion 12 is formed by the injection pressure and the injection heat of the resin material of the covering portion 14. Pressure is applied to the parting line P.
The inner recessed portion 24, which is a portion along L., is crushed to form an acute angle.
【００２５】そして、この被覆部14が固化した状態で、
アシストグリップ11が完成する。Then, in a state where the coating portion 14 is solidified,
Assist grip 11 is completed.

触感を得ることができる。As described above, the assist grip of this embodiment
According to the eleventh aspect, since the inner recessed portions 24, which are recessed in an acute angle toward the outside, are formed to face each other on the inner peripheral portion of the main body portion 12, the hinge portion 20 adjacent to the inner recessed portion 24 is formed. With body part 12
The thickness dimension of the main body 12 is smaller than that of the other portions of the main body 12, so that the main body 12 is easily deformed when grasped, and a good tactile sensation can be obtained.
【００２８】そして、本体部12の外側を覆う軟質の被覆

ソフト感を向上することができる。Since the outer concave portion 21 is formed on the outer peripheral portion of the main body portion 12, the covering portion 14 made of vinyl chloride resin is formed.
The main body 12 and the main body 12 are fitted to each other, the cover 14 is firmly attached to the main body 12, and the idle rotation of the cover 14 can be prevented. Further, since the thickness of the covering portion 14 becomes large in the portion where the outer recessed portions 21 are formed, the outer recessed portions 21 should be set at the positions where the fingers hit when the assist grip 11 is gripped. As a result, the soft feeling of the assist grip 11 can be improved.
