Abstract: A centrifugal clutch that can suppress the inclination of a clutch weight, realize smooth oscillation, and suppress the uneven wear of a clutch shoe is provided. A drive plate (210) slidably supports a clutch weight (230) and also supports a projection body (218) via a projection body support pin (216). The clutch weight (230) includes a first spring attachment part (231) and a second spring attachment part (234) to which two clutch springs (235) are attached formed, and a driven part (238) that comes into contact with the projection body (218) formed. The projection body (218) and the driven part (238) are formed in a manner that a projection body range (TE) where the projection body (218) and the driven part (238) come into contact overlaps action positions (FP1) and (FP2) of forces (F1) and (F2) of the clutch spring (235) acting on the clutch weight (230) in the thickness direction of the clutch weight (230).

Abstract: The present invention relates to a centrifugal clutch (100). The centrifugal clutch (100) includes a drive plate (110) that is rotationally driven directly by the driving force of the engine. The drive plate (110) includes a swing support pin (113) that supports a clutch shoe (123) in a swinging state with respect to a clutch outer part (130), and a spring support (115) that supports a torsion spring (116). The spring support (115) is provided in a standing state on a base (111) adjacent to one distal end (121a) of both end parts of a clutch weight (120) in the circumferential direction that faces a tubular surface (131) of the clutch outer part (130). Both end parts (116b) and (116c) of the torsion spring (116) are respectively hooked on the distal end (121a) of one clutch weight (120) and a proximal end (121b) of the other clutch weight (120) of the two clutch weights (120).

Abstract: A continuously variable transmission that can suppress the size increase, complication, and weight increase of the device configuration is provided. A continuously variable transmission 100 includes a drive pulley 101 that is connected to a crank shaft 90. The drive pulley 101 includes a fixed drive plate 102 that is rotationally driven directly by driving force of an engine and a movable drive plate 110 that approaches or become separated with respect to the fixed drive plate 102 in accordance with centrifugal force by rotational drive of the crank shaft 90. A displacement resistor 120 including a rod body abuts on the movable drive plate 110 in the state in which the fixed drive plate 102 is penetrated. The displacement resistor 120 is pressed by a resistance spring 134 of a pressing mechanism 130 provided outside the fixed drive plate 102. In the pressing mechanism 130, a variable mechanism 140 adjusts pressing force by the resistance spring 134.

Abstract: Provided is a centrifugal clutch having a simple configuration and configured so that a clutch capacity can be increased. A centrifugal clutch (200) includes a drive plate (210) to be directly rotatably driven by drive force of an engine. The drive plate (210) includes swing support pins (214) and protrusions (218). The swing support pin (214) is fitted in a pin slide hole (231) formed at a clutch weight (230), and swingably supports the clutch weight (230). The protrusion (218) includes a cylindrical roller, and contacts a driven portion (235) of the clutch weight (230). The pin slide hole (231) is formed in a long hole shape allowing the clutch weight (230) to displace backward in a rotary drive direction of the drive plate (210). The driven portion (235) is formed to extend inclined outward to a rear side in the rotary drive direction of the drive plate (210).

Abstract: A centrifugal clutch 200 includes a first drive plate 210 rotationally driven directly by a driving force of an engine and a second drive plate 220 frictionally in contact with the first drive plate 210. The first drive plate 210 includes a bulging body 215 on a supporting portion 214 bulging toward the second drive plate 220. The second drive plate 220 is rotationally driven together with the first drive plate 210 while allowing rotational displacement relative to the first drive plate and includes clutch weights 230. The bulging body 215 is made of a cylindrical roller. The clutch weight 230 is formed with a driven portion 232. The driven portion 232 has a pressing body 232a in contact with the bulging body 215. The pressing body 232a obliquely extends rearwardly and outwardly in a rotational drive direction of the first drive plate 210.

Abstract: A work region evaluating system includes an imaging unit and a processing unit. The processing unit includes an image processing section that converts a three-dimensional image of a vehicle body component recorded by the imaging unit to three-dimensional image data, an extraction section that extracts work regions and reference regions respectively from both the three-dimensional image data and three-dimensional design data, an alignment section that aligns the three-dimensional image data with the three-dimensional design data with reference to the reference regions, and an evaluation section that evaluates a relation between the work region extracted from the three-dimensional image data and the work region extracted from the three-dimensional design data, based on the three-dimensional image data and the three-dimensional design data which are aligned with each other by the alignment section.
