Abstract: PROBLEM TO BE SOLVED: To provide a lamp in which the deformation of the front end edge of a guide part caused by thermal expansion is reduced. SOLUTION: In order to guide suspension arms to housing places 27 by sliding the arms, at least two guide parts 28 individually formed for each suspension arm by using a polymeric material with a small coefficient of friction, and a guide supporting member 71 formed by using a material with a coefficient of thermal expansion smaller than that of the polymeric material of the guide parts 28 to support each guide part 28 in a prescribed position, are provided. The guide supporting member 71 has recessed parts 72 engaging with each guide part 28 in the position which is in the area contacting each guide part 28, does not contact a recording disk and the distance to the front end 29 of each guide part 28 is shortest. Each guide part 28 has a projecting part to support the guide parts 28 in the position suitable for guiding the suspension arms by engaging with the recessed parts 72.

Abstract: PROBLEM TO BE SOLVED: To provide a lamp which does not give rise to the trouble that the lamp is deformed and shaken by creep formation by resin molding alone without using metallic parts. SOLUTION: The lamp 200 is composed of a mounting section 221 which is formed by using a high-polymer material so as to have screw holes 25 for fixing the lamp to a casing of the information recording disk device by using screws and an arm holding section 222 which is formed by using a high-polymer material of a small coefficient of friction so as to have a stowage section 27 for holding a suspension arm in the state of parting the same from a recording disk and a guide section 28 for facilitating the putting of the suspension arm into and out of the stowage section 27 by oscillating the suspension arm. The mounting section 221 and the arm holding section 222 are integrated by molding these sections before and behind each other.
