摘要:
The present invention provides a steering apparatus having simple construction, and good left and right balance of the clamping force, such that the clamping force does not fluctuate depending on the forward-backward position of the steering wheel 103. When fastening the tilt and telescopic function, by rotating an operation lever 349, the peak of a movable cam 344 runs over the peak of a stationary cam 343, which pushes the stationary cam 343 to the right side, and pulls a clamping rod 34 to the left side at the same time, so as to clamp side plates 32A, 32B. The inside surfaces 321A, 321B of the side plates 32A, 32B clamp flat surface section 61A, 62B of a distance bracket 6. The flat surface sections 62A, 62B elastically deform toward the inside in the width direction of the vehicle, and a pair of left and right clamping sections 66A, 66B of bent sections 64A, 64B clamp the outer circumferential surface of an inner column 2 from both the left and right sides.

The present invention has an objective to easily obtain an emulsion exhibiting superior storage stability, and in particular, an emulsion of a polyorganosiloxane. The present invention provides a method for producing an emulsion characterized by obtaining an emulsion by emulsifying a mixture of an oil and a surfactant, obtained by synthesizing the surfactant in the oil. In particular, the method is suitably used for the preparation of an emulsion of an organopolysiloxane (A) which is usually difficult to be stably emulsified. A silicone-based surfactant (B), and in particular, a silicone-based surfactant having a small degree of polymerization of a siloxane chain such as a trisiloxane is synthesized in an oil. Thereby, an emulsion exhibiting superior storage stability can be produced.

An oil-in-water silicone emulsion composition comprising (A) 100 mass parts of a polyorganosiloxane that contains in each molecule at least two groups selected from the group consisting of the silicon-bonded hydroxyl group, silicon-bonded alkoxy groups, and silicon-bonded alkoxyalkoxy groups, (B) 0.1 to 200 mass parts of a colloidal silica, (C) 0.1 to 100 mass parts of an aminoxy group-containing organosilicon compound that contains at least three silicon-bonded aminoxy groups in each molecule, (D) 0.1 to 50 mass parts of a surfactant, and (E) 10 to 200 mass parts water. Such oil-in-water silicone emulsion composition that contains little low molecular weight silicone can form, even without the use of a tin catalyst, a cured film that exhibits a satisfactory strength and a satisfactory adherence to substrate, through the removal of the water fraction.

A camera with a cartridge chamber for accepting a film cartridge with film and a cover for covering the cartridge chamber. The camera has a locking mechanism that locks the cover when the cover is in a closed state and a releasing device for releasing the cover from a closed state. The locking mechanism includes a pivotable member having on one end a locking portion engageable with the cover to lock the cover in the closed state and on the other end a contact portion. A biasing member urges the pivotal member in a locking direction so that the locking portion engages the cover. The releasing member includes a motor is used to open the cover. The motor drives a crank member that is connected to an unlocking member via a link member, which is operable to rotate the pivotal member in a direction opposite to the cover closing direction to open the cover.

A shock-absorbing member 18a comprises combined held sections 33 that are located at a plurality of locations in the circumferential direction and that comprise paired held sections 25a, 25b, and is constructed so as to have a non-circular cylindrical shape in the cross section by arranging portions where outer-diameter side end sections of the held sections 25a, 25b that are adjacent to each other in the circumferential direction are made continuous by way of outer-diameter side cover sections 31, and portions where inner-diameter side end sections of the held sections 25a, 25b that are adjacent to each other in the circumferential direction are made continuous directly or by way of inner-diameter side cover sections 32, in an alternating sequence in the circumferential direction. Drive-side arm sections 21a are placed between the paired held sections 25a, 25b, driven-side arm sections 23a are placed between the combined held sections 33, and the outer circumferential surfaces of the drive-side arm sections 21a are covered by the outer-diameter side cover sections 31.
