Abstract: This invention relates to a view angle adjustment mechanism. A view element tilting section is tiltably supported by a tilting support section via an inner pivot and an outer pivot. The view element tilting section includes a view element holder holding a view element. The inner pivot and the outer pivot are formed between the tilting support section and the view element holder. The outer pivot has a structure in which an outer-pivot convex surface formed at the view element holder and an outer-pivot concave surface formed at the tilting support section are slidably fitted together. The outer-pivot convex surface is formed in an outer circumferential surface of an outer-pivot convex surface-forming annular wall formed at a back surface of the view element holder in an integrated manner.

Abstract: A tire air filling device according to one embodiment includes a cylinder having a first opening communicating with a tire; and a weight that is provided inside the cylinder, that has an air flow hole through which air to be supplied to the tire passes, and that moves in an axial direction of the cylinder upon a receipt of a centrifugal force, to supply the air from the first opening to the tire. The tire air filling device includes a weight spring interposed between the weight and an inner surface of the cylinder; and an inclined member attached to a check valve that prevents a backflow of the air from the tire to an inside of the cylinder, and to the cylinder in a state where the cylinder is inclined with respect to the check valve.

Abstract: This invention relates to a view angle adjustment mechanism that causes a view element tilting section holding a view element to be supported by a tilting support section via a plurality of concentric pivots having different diameters, to perform view angle adjustment. An inner pivot is assembled by forcible fitting using elasticity of either or both of a pivot convex and a pivot concave without screw fastening. An outer pivot includes a plurality of elastic pieces disposed at a plurality of positions in a circumferential direction of a curved surface of either or each of both of an outer-pivot convex surface and an outer-pivot concave surface. The outer pivot is assembled by the forcible fitting in the inner pivot. The assembly causes the plurality of elastic pieces to elastically abut on an opposed curved surface.

The tire air filling device includes a weight airtight member interposed between the weight and an inner surface of the cylinder; and a weight spring that biases the weight to a side opposite to the tire. The cylinder has a second opening on a side opposite to the first opening, and a cap that is detachably attached to the second opening is provided.

Abstract: This invention relates to a view angle adjustment mechanism that causes a view element tilting section holding a view element to be supported by a tilting support section via a forcible fitting-type pivot to perform view angle adjustment. A pivot is assembled by forcible fitting between a pivot convex and a pivot concave. The pivot convex includes a spherical surface. The pivot concave includes a surface formed by arranging two conical surfaces so as to face in respective directions opposite to each other along a center axis X of the pivot concave. The spherical surface of the pivot convex is inscribed in the two conical surfaces of the pivot concave.

Abstract: This invention relates to a view angle adjustment mechanism. A view element tilting section is tiltably supported by the tilting support section. Upon a motor being driven, a nut member rotates together with a gear member, the nut member rises/falls along a male thread member, whereby the view element tilting section is tilted. At a barrel of the nut member, a protrusion is formed. The protrusion is fitted in a groove of the gear member and causes the nut member to rotate together with the gear member. At the tilting support section, a protrusion abutment portion is formed. When the nut member moves in a direction in which the nut member comes off from the male thread member, the protrusion abutment portion abuts on the protrusion and thereby prevents movement of the nut member.
