Abstract: A rear-wheel toe angle variable vehicle changes a toe angle of a rear wheel by a rear toe actuator including: a housing connected to one of a rear-wheel support member and a body; a motor in the housing; a rod connected to the other of the rear-wheel support member and the body; a nut provided in one of the housing and the rod; a screw shaft provided in the other of the housing and the rod; a rotation transmission unit in the housing for transmitting rotation of the motor to the nut or screw shaft; and a rotation amount detection unit for detecting a rotation amount of one of the rotation transmission unit and the nut or screw shaft. The vehicle estimates an operation amount of the rear toe actuator based on the detected amount, and performs feedback control of the motor using the estimated amount.

Abstract: An insertion part of an endoscope includes at least a bending portion and two portions connected to one and the other ends of the bending portion. A bending structure of the bending portion is connected at its other end adjoining area overlapping with an adjoining area of at least one of the two portions to the adjoining area of the at least one of the two portions by a fixing member. A thread member wound on an end portion of a flexible covering member covering the bending structure, the end portion corresponding to the fixing member, has a pulled-in part arranged between the outer peripheral surface of that end portion of the cover member and a winding portion formed by the wound thread member, and the pulled-in part is arranged in a side of the fixing member. The winding portion of the thread member is covered by a resin layer.

Abstract: An endoscope having an elongate insertion section to be inserted into a body cavity with a distal end portion thereof forward. The endoscope comprises a tip member provided on the distal end portion and having a housing bore extending from a rear end side to a distal end side, a protrusion on an inner peripheral surface of the housing bore, and an optical member which is inserted into the housing bore from the rear end side and fixed to the tip member with the distal end portion thereof run against the protrusion.
