Abstract: A heat insulating vessel for a low temperature liquefied gas pump, which includes an inner tank configured to accommodate low temperature liquefied gas, an outer tank provided externally around the inner tank, and a low temperature liquefied gas pump disposed inside the inner tank. The outer tank has an outer tank upper part that is an upper end portion thereof, and an outer tank body other than the outer tank upper part. A lid structure having a heat-insulated structure detachably fitted into an upper part of the inner tank. The pump is fixed to the lid structure, and a suction pipe and a discharge pipe are insertedly fixed to the lid structure. A vacuum insulating layer is provided between the inner tank and the outer tank. With this heat insulating vessel for the low temperature liquefied gas pump, adiabaticity of the lid structure and maintainability of the pump are increased.

Abstract: A valve gear for an engine, includes: a camshaft phase varying device by which a rotational phase of a camshaft for opening/closing valves of the engine can be changed relatively to that of a crankshaft; and a holder that is provided so that the holder can be removably attached to the camshaft in a state where the holder has held constituent components of the camshaft phase varying device.

Abstract: A damper restricts pivot pin rotation associated with operation of an operating section, wherein friction resistance that impedes the pivot pin rotation is changed in stepped fashion. When the pivot pin rotates in direction ? due to depression of an accelerator pedal, a slide cam shifts an edge section of an inclined cam surface away from a rotating cam while staying in contact with a gradual first inclined region of the rotating cam's inclined cam surface. Torque around the axis of the pivot pin is produced, the entire region of the slide cam's inclined cam surface comes into contact with a steep second inclined region of the rotating cam's inclined cam surface upon accelerator pedal depression to a prescribed position (the pivot pin has rotated by a prescribed angle ?1 in direction ?), and the torque around the axis of the pivot pin rapidly increases.

Abstract: Provided is a damper configured so that a compact pedal unit can be obtained using the damper and so that the damper can be easily retrofitted to a pedal unit. A damper (1) comprises elements such as: a pair of cams (slide cam (4) and stationary cam (5)) which rotate relative to each other about the axis (O1) to cause the sloped cam surfaces (4132, 5211) thereof to make sliding contact with each other; a coiled spring (3) which presses the sloped cam surface (4132) of the slide cam (4) against the sloped cam surface (5211) of the stationary cam (5); a case (2); and a resin roller (8) which is fitted in a rotatable manner on the shaft (7A). The rotational motion of the slide cam (4) about the axis (O1) is restrained by the case (2), and as a result, the slide cam (4) rotates about the axis (O1) relative to the stationary cam (5) in association with the rotation of the case (2) about O1.

Abstract: The present invention enables a user to intuitively grasp the occurrence of prescribed phenomena during operation. Provided is a damper that restricts pivot pin (4) rotation associated with operation of an operating section, wherein the friction resistance that impedes the rotation of the pivot pin (4) is changed in a stepped fashion. When the pivot pin (4) rotates in direction ? due to the depression of an accelerator pedal (operating section) (21), a slide cam (62) shifts an edge section (621A) of an inclined cam surface (621) in a direction A away from a rotating cam (61) while staying in contact with a gradual first inclined region (611A) of an inclined cam surface (611) of the rotating cam (61).
