Abstract: An object is to enable a compact and high output heat storage system to perform warm-up rapidly when a vehicle is started up, and after warm-up, to recover surplus heat that is present in a heat source in the vehicle to prepare for the next warm-up event. A heat recovery-type heating device includes: an ammonia buffer configured so as to be capable of fixing and desorbing ammonia that serves as a chemical reaction medium; and a chemical heat storage reactor provided with a chemical heat storage material that generates heat through a chemical reaction with ammonia supplied from the ammonia buffer, and that desorbs ammonia using surplus heat from a heat source and returns the ammonia to the ammonia buffer.

Abstract: When temperature of lubricating oil is raised at a time of low-temperature, of an outer peripheral side of a radial plain bearing in a bearing retaining unit, heat is not supplied from a heating medium in a thermal medium flow path on the outer peripheral side of a halved bearing metal in a bearing retaining unit body, which has a large thermal capacity, and instead, heat is supplied from the heating medium in the thermal medium flow path on the outer peripheral side of a halved bearing metal in the cap, which has a small thermal capacity.

Abstract: A sliding support structure includes: a support member (12; 106) and a shaft member (10; 120) that relatively rotates with respect to the support member (12; 106) wherein lubricating oil is supplied to between a sliding surface of the shaft member and a sliding surface of the support member, the support member (12; 106) has a sliding surface portion (x) that corresponds to a load concentrating portion between the shaft member (10; 120) and the support member (12; 106), and sliding surface regions (Ya, Yb) that are higher in oil repellency than the sliding surface portion are respectively provided on upstream and downstream sides of the sliding surface portion in a flow direction of the lubricating oil.
