ENGINE WITH BREATHER APPARATUS

摘要

In order to suppress freezing of a water content within a breather tube, a heater (13) is arranged within a breather tube (11) joining a cylinder head cover (10) and an air cleaner (8). A main body of the breather tube (11) is constituted by a joint tube (18) arranged in a middle, and partial tubes (22, 23) connected to both ends thereof. The heater (13) has a heating element (14) corresponding to a heating element, and has a heater case (21) accommodating the heating element (14) in a state of being pinched by electrodes (15 ), and is arranged in a center portion of the joint 18. A slot (18a) for inserting the heater (13) is formed in the joint tube 18. A heat radiating body (20) extended along the breather tube (11) is joined to the heater case (21) . An outer peripheral portion of the breather tube (11) is covered by an insulative outer tube (24).
