Abstract: A seat structure capable of dealing with both a normal posture and a resting posture and providing sufficient relaxation in the resting posture while ensuring excellent comfortableness of an occupant. According to the present invention, a back frame 20 itself is fixed to a frame support 10 but a cushion frame 30 shifts from a first position A to a second position B according to an occupant's movement and an inclination angle of a pelvis support 31 increases accordingly. The occupant's pelvis portion and a portion lower than the pelvis portion is moved forward but a part of his or her back above his or her breast is not varied. With this structure, the same effect of the resting posture, that is, the posture in which the back frame is reclined in a conventional seat structure, can be obtained. Since the back is not tilted backward, a leg room (footrest) space in a rear seat is not limited.

Abstract: It is an object of the invention to provide an effective technique for reducing the manufacturing costs of a handle mounted to a power tool. According to the invention, a representative handle may comprise a handle body, a grip, an elastic element and an elastic outer surface member. The grip is hollow-shaped and the handle body is inserted into the grip. The elastic element is disposed between the inner surface of the grip and the outer surface of the handle body to apply a biasing force to the grip upon movement of the grip with respect to the handle body when vibration of the power tool is transmitted from the handle body to the grip. The elastic outer surface member covers the outer surface of the grip. The elastic outer surface member is integrally formed with the elastic element. As a result, the manufacturing costs can be reduced compared with known construction in which the elastic outer surface member and the elastic element are separately formed.
