Abstract: A power supply rail includes a groove extending in a first direction in a base portion and having an opening on a one-end side in a second direction, a conductive portion provided at a bottom surface of the groove, and a first recess formed on a first side wall of the groove. A power supply terminal is attachable/detachable into/from the groove, and includes terminal portions formed on an other-end side in the second direction of a body portion, a lead-wire portion from the terminal portions and elastic portions provided on a first side surface of the body portion. The elastic portions are latched in contact with an inside of the first recess of the power supply rail, and the terminal portions contact with the conductive portion.

Abstract: This support apparatus includes a fixation member and a support member attachable to and detachable from an opening portion of the fixation member. A first upper surface portion of the opening portion is formed of: a first front surface portion sloped in a downward direction; and a first rear surface portion formed continuously from the first front surface portion and sloped in an upward direction. A first lower surface portion is sloped in parallel with the first front surface portion. A second upper surface portion of the support member is formed of: a second front surface portion to contact the first front surface portion; and a second rear surface portion to contact the first rear surface portion. A second lower surface portion is sloped in a downward direction, at a slope angle, so as to contact with an opening-side end of the first lower surface portion.

Abstract: A fixture member includes: a pillar having a substantially horizontal sectional shape that is a U-shape; a plurality of chip portions fixed in the pillar; and an opening formed by a lower surface of one chip portion, an upper surface of another chip portion, and opposed inner side surfaces of the pillar. A support member is detachably attached to the opening. A receiving member is fixed to the support member. The chip portion has an upper slope surface, a first horizontal surface, and a lower slope surface. The support member has: a first contact surface to contact with the lower slope surface; a second contact surface to contact with the upper slope surface; a third contact surface to contact with the first horizontal surface; and a fourth contact surface and a fifth contact surface to contact with the opposed inner side surfaces of the fixture member.

Abstract: A lighting apparatus that enables a wide range to be irradiated and enables the light irradiation angle to be easily changed includes a fixation unit and a lighting unit attachable to and detachable from the fixation unit. The fixation unit includes: a first mounting portion having an arc surface having an arc-shaped cross section perpendicular to a longitudinal direction such that the arc shape is continuously formed along the longitudinal direction; and a fixation portion for fixing the first mounting portion. The lighting unit includes: a light source portion formed along the longitudinal direction; a holding portion holding the light source portion; and a second mounting portion provided along the longitudinal direction on the holding portion and having a mounting surface to be magnetically attached at any position in the circumferential direction on the arc surface of the first mounting portion. The second mounting portion is formed by a magnet.
