Abstract

An object of the present invention is to provide a compressor and a turbocharger whereby it is possible to suppress breakage of a bolt fastening a frame adjacent to a scroll-chamber frame and the scroll-chamber frame effectively and to join the frames stably. A compressor (10) includes: an impeller (14) for compressing air; an air-guide cylinder (16) for housing the impeller (14) and guiding the air; a scroll-chamber frame (20) disposed adjacent to the air-guide cylinder (16), the scroll-chamber frame (20) forming a scroll chamber (18) for guiding the air having passed through the air-guide cylinder (16) to outside; a frame (22, 40) disposed adjacent to the scroll-chamber frame (20); a bolt (25, 48) for fastening the scroll-chamber frame (20) and the frame (22, 40); and a spacer 28 disposed between a head portion (26, 52) of the bolt (25, 48) and the scroll-chamber frame (20).

Description

[0001] This application is a divisional application of the following application: [0002] Filing date of the original application: June 30, 2014 [0003] Application number of the original application: 201480041368.0 [0004] Invention title of the original application: compressor and supercharger technical field [0005] The invention relates to compressors and superchargers for internal combustion engines. Background technique [0006] Conventionally, as a supercharger for compressing air supplied to an internal combustion engine, a supercharger including a compressor including: an impeller for compressing air; an air guide cylinder for accommodating the impeller and guiding air; and a swirl chamber frame which is provided adjacent to the air guide cylinder and forms a swirl chamber for guiding the air passing through the air guide cylinder to the outside. [0007] In the turbocharger described in Patent Document 1, when a part of the impeller bursts and is scattered o...
