Abstract: An easy-assembly bed includes a top plate, and a leg portion having a plurality of leg members that are linked using notched joints. The top plate is constituted of a bonded material, which includes a plate-shaped foam plate formed with a foam body, and a front board member and a rear board member having an identical shape to the foam plate and that are bonded to the rear surface and the front surface of the foam plate, respectively, and a top plate molded resin portion overing the cut ends of the bonded material with a molded resin; and the leg members are each constituted of a grooved bonded material, which includes a plate-shaped grooved foam plate having locking grooves and formed with a foam body, and a grooved front board member and a grooved rear board member on the front surface and the rear surface of the grooved foam plate.

Abstract: A wiper device equipped with a rise up mechanism, including a motor, a blade, a wiper pivot, a motor arm which rotates in one direction during the starting and wiping operations of the blade and which rotates in a reverse direction during the parking and stopping operations of the blade, a connecting rod reciprocating in response to the rotation of the motor arm to swing the wiper pivot, a retainer for retaining the connecting rod, an eccentric member for rotating together with or relative to the retainer, a friction spring disposed between the eccentric member and the retainer for permitting the rotation of the eccentric member relative to the retainer only just after the starting of the blade or just before the parking and stopping of the blade, and a cam mechanism for rotating the eccentric member together with the retainer during all operations except the operation during which the eccentric member rotates relative to the retainer just after the starting of the blade or just before the parking and stoppin
